Planet Sport Bet Boost: Spain, Republic of Ireland and Portugal all to win now 7/2

Planet Sport's latest bet boost turns its attention towards World Cup qualifying, where a Spain, Republic of Ireland and Portugal win treble is now at 7/2.

The international break is never as exciting as club football, but with World Cup qualifying coming to a somewhat climactic close, there's certainly a few worthwhile games on show.

To take advantage of Sunday's qualifying matches, Planet Sport are offering customers a bet boost that sees Spain, Republic of Ireland and Portugal all to win rise from 3/1 to 7/2.

Spain vs Sweden

Spain, Pablo Sarabia, World Cup qualifiers

Our first selection sees the top two teams in Group B come face-to-face.

Luis Enrique's Spain currently sit top on 16 points, but Sweden follow closely behind with 15. Both sides enter the match knowing a win secures their spot in the World Cup next year.

Spain's only loss in qualifying came against Sweden back in September, when Carlos Soler's early goal was cancelled out by Alexander Isak and Viktor Claesson's strikes.

However, Enrique's side have since picked up form, and despite losing the Nations League final to France back in October, they performed well to beat Italy in the semi-finals, and picked up wins against Georgia, Kosovo and Greece in qualifying.

With home advantage, and knowing a win is enough to send them to Qatar next year, Spain should have enough to see off Sweden in Seville.

Luxembourg vs Republic of Ireland

Republic of Ireland, World Cup qualifiers

It's already been confirmed that neither Luxembourg or Republic of Ireland will be competing in Qatar next year, but a win for Stephen Kenny's side leapfrogs the Irish above Luxembourg in the standings.

Ireland started qualifying poorly by losing their opening two games, the first a 3-2 loss to Serbia before a 1-0 defeat to Luxembourg in the reverse fixture.

They lost away to Portugal, which was probably to be expected, but at 2-1 they did well to keep themselves in the game.

Since then, they've gone five games unbeaten, including the impressive 0-0 draw against Portugal last Thursday.

Having seemingly turned a corner from the start of their qualifying campaign, Ireland should have enough to overcome Luxembourg on their travels this Sunday.

Portugal vs Serbia

Another crucial match takes place this Sunday when the joint-leaders of Group A face off in Lisbon.

Portugal lead the group, but only on goal difference, Serbia are joint on points with 17.

In the reverse fixture, Liverpool's Diogo Jota handed Portugal a two-goal lead in the first half, but Serbia fought back through Aleksander Mitrovic and Filip Kostic to rescue a point.

Since then, Portugal have gone seven games unbeaten in qualifying, with the only draw being Thursday's stalemate with Republic of Ireland.

Serbia are also unbeaten in the group, and they too tripped up against Ireland back in September when Nikola Milenkovic's late own-goal meant they only took home a point.

It's all to play for on Sunday evening, but with experience and talent in abundance in the Portugal squad, they have the ability to see off Serbia and secure their place in the World Cup next year.

The loser of the game could yet join them in the tournament, but will have to go through the play-offs first.
