Five fantasy questions ahead of Gameweek 6, including whether to captain Ronaldo or Salah

Ole Gunnar Solskjaer's Manchester United saw off West Ham after a dramatic final few minutes, and despite Cristiano Ronaldo not hogging all the headlines, he still brought home a healthy haul of points.

As did Liverpool's Mohamed Salah, who continued his strong start to the season with a goal and an assist in their 3-0 dismantling of Crystal Palace.

The news wasn't quite as positive for owners of Luke Shaw and Trent Alexander-Arnold, though. The two highest-owned defenders registered a measly two points between them, with Liverpool's young star left out of Jurgen Klopp's squad due to illness.

However, regardless of whether your team raked in the points or failed to impress, it's time to look forward to another week of action, and a whole new set of head-scratching questions.

How do I choose this week's captain?

Ah, the weekly headache that is choosing a captain. After making your transfers and finally feeling content with your squad, that feeling of calm instantly evaporates when it comes to handing over that precious armband.

However, while it may be a difficult choice, the fantastic form of three individuals helps to narrow down our options.

Of course the three players in question are Manchester United's Cristiano Ronaldo, Liverpool's Mohamed Salah and Chelsea's Romelu Lukaku.

While there are very few teams out there boasting all three big-hitters, there'll be plenty of you out there owning two of these goalscoring machines, and we think there's more logic to the decision than simply flipping a coin.

Salah currently leads the way in terms of goals, with the Egyptian on four, one more than Ronaldo and Lukaku.

However, having achieved his tally in just two Premier League appearances, it's United's Portuguese star that holds the best goal-to-game ratio.

In comparison, Chelsea's big Belgian forward has scored three in four games, but blanked against Spurs this weekend - albeit with a little help from Timo Werner's wayward shooting.

However, with Manchester City up next for the Blues, Lukaku will find it hard to impact the match again and will fall further behind his attacking rivals.

The other early kick-off on Saturday sees United go head-to-head with Aston Villa at Old Trafford. It's certainly an appealing game for Ronaldo's points haul, but nowhere near as enticing as Liverpool's afternoon clash against Brentford.

Jurgen Klopp's side has looked as lethal as ever, and that's with an out-of-form Diogo Jota spearheading his attack. With Sadio Mane starting to find form too, Liverpool could sting the Bees this weekend and Salah will inevitably chip in.

So it's Liverpool's No. 11 that gets the nod for our captaincy this week. However, if he's not found his way into your team - somehow - then Ronaldo isn't a bad fallback option.

Are Arsenal players now worth considering?

After their torrid start to the season, Arsenal are slowly but surely getting to grips with the new season, registering back-to-back 1-0 wins.

It's not been overly convincing, but Mikel Arteta's side are showing they can get the job done, and with clean sheets, too.

Having scored just the one goal against Norwich and Burnley, Arsenal's attack doesn't hold much appeal, but they've shown a vast improvement in defence.

Both Ben White (£4.4million) and Takehiro Tomiyasu (£4.5million) have starred in the wins, and been pivotal in the improved defence. And, at such low prices, are well worth considering at the back.

Additionally, for those with a little more room for manouevre in their budget, Kieran Tierney (£4.9million) has not only been reaping the rewards from Arsenal's clean sheets, but also looks a major attacking threat down the left.

If you're still not convinced by the Gunners, then Sunday's clash against north London rivals Tottenham Hotspur will be a much better gauge of their defensive capabilities.

Following the derby clash, Arteta's side embark on a healthy run of fixtures against Brighton, Crystal Palace and Aston Villa, where more clean sheets look likely.

Will Chelsea's defence remain watertight?

After sealing a 3-0 win against London rivals Tottenham Hotspur this week, Chelsea have now kept more clean sheets (15) than they have conceded goals (14) since the arrival of Thomas Tuchel.

His rigid and organised system has worked wonders in the Premier League and, as a result, Chelsea defenders are bringing in points by the bucketload.

Antonio Rudiger's performance against Spurs saw him awarded a remarkable 14 points this week after scoring and keeping a clean sheet, and he's certainly caught the eye of fantasy managers.

Furthermore, Marcos Alonso (£5.7million) has seen his career rejuvenated under Tuchel and is enjoying a good spell of form at left wing-back, while Thiago Silva (£5.4million) and Cesar Azpilicueta (£6million) are also valuable options.

The Blues first have to overcome the difficult challenge of playing Pep Guardiola's Manchester City side at home this weekend.

And, while they may have failed to break the deadlock against Southampton, City have a knack for bouncing back in style, and Chelsea's defence will likely be breached on Saturday afternoon.

Is it too late to put Sarr in?

Watford's Ismaila Sarr turned out to be the surprise package of gameweek five after scoring twice against Norwich in a 3-1 win.

The 23-year-old rewarded his owners with an impressive 15 points, making him one of the week's highest points-scorers, but was it all just a flash in the pan?

The Hornets have coped better than most anticipated in the top flight so far, and it's much to the credit of Sarr, who has scored in both of Watford's wins.

Xisco Munoz' team looks threatening going forward, and with favourable fixtures against Newcastle United and Leeds United up next, Sarr could thrive.

Newcastle and Leeds only trail Norwich in terms of goals conceded this season, while Watford currently sit ninth in the scoring charts.

With goal-fests on the horizon, it's definitely not too late to bring in Sarr, who at £6.1million, is beginning to look like a midfield bargain for any side.

Should I transfer out Trent Alexander-Arnold?

Liverpool's star right-back is the second most popular defender in fantasy with a 35.2% ownership, but the 22-year-old left his owners with an agonising blank this week after missing out through injury.

However, Klopp dampened the spirits of thousands of managers on Saturday afternoon after announcing that Alexander-Arnold was out injured for their clash against Crystal Palace - thanks for the warning Jurgen.

As a result, managers saw the £7.5million-rated defender drop to their bench.

With managers in the dark about whether he'll return next week, it is understandable many managers are contemplating selling the game's most expensive defensive asset.

With the illness likely to be short-term, we're advising you to hold your nerve and stick with Trent for this week - it's far too risky to miss out on his potential points if he returns for the Brentford clash.
