Arsenal boss Mikel Arteta will be hoping his remaining World Cup stars return to the club fit and healthy.
After losing forward Gabriel Jesus to a knee injury, the last thing Arteta needs is to lose more players.
Arsenal have been sensational this season, and deservedly sit top of the Premier League.
The World Cup break has given Arteta’s side a chance to recoup, but may impact their impressive form.

A number of players earned spots at the World Cup thanks to their performances at the Emirates.
Bukayo Saka has made himself a key figure in Gareth Southgate’s England side, and already has three goals in Qatar.
Brazilian Gabriel Martinelli also squeezed into Tite’s squad, ahead of the likes of Liverpool’s Roberto Firmino.
Sport’s report now states that Barcelona have been watching Martinelli closely at the World Cup.
The 21-year-old’s contract situation at Arsenal is giving Xavi’s side a reason to look in the winger’s direction.
Barcelona are watching Martinelli in Qatar
The report states that Barcelona have been closely following Martinelli this year, and have been impressed by his ‘exceptional season’.
Barcelona believes that if Martinelli doesn’t renew his contract soon, there could be a ‘real market opportunity’.
However, Sport suggest that a move is unlikely right now, with Arsenal and Martinelli both keen to extend his stay in north London.
The winger is currently on £47,000-a-week, and could sign a new four-year deal that increases that significantly.

Martinelli has been sensational this season, and already has five league goals and two assists.
Arsenal legend Ian Wright has admitted he’s been surprised by just how good the Brazilian has been this season.
Journalist Fabrizio Romano believes Arsenal have stepped up their efforts to extend Martinelli’s contract recently.
Given Barcelona are closely watching Martinelli in Qatar, Arteta will be keen to conclude any contract talks quickly.
