The 25-year-old broke into Leeds United's first team during the club's chaotic period under Italian owner Massimo Cellino.
Over the years, Phillips has solidified his place in the starting line-up and even helped the Whites to Premier League promotion during the 2019/20 season.
The midfielder is now a regular starter for the England national team and even played in every game during the country's Euro 2020 campaign.
With high success, interest undoubtedly follows.
Phillips is on the radar of numerous clubs and a move away from Elland Road is not out of the question in the next transfer window.
Leeds have enjoyed a lot of success under Marcelo Bielsa but they're unlikely to be playing Champions League soccer anytime soon.
With that in mind, it's possible that we could see the Leeds-born player continue his career at one of the Premier League's powerhouses. Question is, which one?
Manchester City 7/4
Manchester City are currently the favourites to get the midfielder's signature. However, their recent transfer record leaves a lot to be desired.
With Fernandinho's contract coming to an end next summer, the Cityzens will be hoping to do a better job replacing the Brazilian with another highly rated midfielder.
Phillips is rumoured to be at the top of Guardiola's wish list which doesn't come as a surprise considering the player's consistent performances for club and country.
The Leeds academy graduate would be a great addition to City's squad. What's more, the appeal of Champions League soccer and an assured push for trophies will also play a major factor.
Manchester United 10/3
The other Manchester club are also in the running and Planet Sport Bet currently have them as second favourites.
The strong rivalry between Leeds and Man United has never stopped the two clubs from doing business. Alan Smith, Lee Sharpe, Gordon Strachan, Rio Ferdinand, Johnny Giles, Eric Cantona and most recently, Daniel James, are just some of the players who have represented both teams.
Kalvin Phillips wears his heart on his sleeve and is Leeds United through and through. However, the prospect of playing alongside the likes of Cristiano Ronaldo, Paul Pogba and Bruno Fernandes must be tempting.
The prospect of winning trophies and competing at the pinnacle of the sport - even though Leeds have won more than United over the last three years - would catch the eye of anyone looking to take their career to the next level.
What's more, Man United will soon need to make additions in midfield. Nemanja Matic is far from his prime while Fred has not always been consistent for the Red Devils.
With that in mind, a Phillips transfer to Old Trafford cannot be ruled out.
On paper, a move to Anfield seems more likely for Phillips than a move to Old Trafford.
In reality, the fact that Liverpool refuse to splash the cash could hamper a possible deal for the 25-year-old.
There is a feeling that Jurgen Klopp would be the perfect manager for a player of Phillips' calibre. What's more, with the likes of Jordan Henderson and Thiago Alcantara hitting their 30s, the Leeds man would inject an element of youth and energy into the team's middle line.
Nevertheless, with the player valued at around £36million, economics might be the single issue which scuppers a deal from being done.
Money is certainly not an issue with regards to Chelsea. In fact, if the Blues wanted to sign the player, we're pretty sure they would have already done the deal.
Instead, the problem for the Blues is the abundance of talent already in the squad. With the likes of Jorginho, N'Golo Kante, Mateo Kovacic and now Saul in the team, where would Phillips come into the picture?
Thomas Tuchel is stacked for talent across all positions and it's no surprise to see the Blues priced as far as 7/1.
From one team that can't handle any more talent to one that could certainly use some.
A total of six players were ruled out before Tottenham's clash with Crystal Palace last weekend. Nuno Santo tried to do the best with what he had left but ultimately, his attempts proved unsuccessful as Palace romped to a 3-0 win.
One of the bright young sparks in the Spurs midfield is Oliver Skipp but he alone can't save this Tottenham side from continuous averageness.
The addition of Phillips would be a major boost to the team but the question is, why would the player leave a club he loves for one that doesn't even compete in Europe - no, we're not counting the UEFA Conference League.
If by some miracle Spurs become competitive over the next 12 months, their odds in this market may change. For now, they're rightfully outsiders.
The Gunners are in a bigger mess than Spurs and the same argument can be applied here.
Leeds might not be pushing for the top four anytime soon but neither are Arsenal. With that in mind, why would Phillips leave the Whites for a team that appear to be in complete chaos.
With that in mind, it's no surprise to see Arsenal priced as high as 16/1.
