After both made positive starts to their respective Chelsea careers last season, Brazil international Willian and German star Andre Schurrle have found themselves competing for a place in the Chelsea team.
With Eden Hazard and Oscar certain of their positions in the Chelsea formation, only one place is left for either Willian or Schurrle to make their own. So far this season, Schurrle has looked the favoured choice by manager Jose Mourinho, starting four of the Blues' opening seven fixtures, whilst Willian has started three.
Last season was the same with Willian making 42 appearances in all competitions for the club, whilst Schurrle made 44, although the former started more. In terms of goals, German World Cup winner Schurrle was the clear winner.
Despite being in and out of the Chelsea team, he managed to score eight league goals and one Champions league goal, including a hat-trick against Fulham and important strikes against Manchester City and Paris Saint Germain.
Willian netted a poor tally of just four goals in his debut season in England, with his lack of prowess in the final third the one weakness of his almost complete game according to his manager.
Schurrle, 23, was bought for £18 million from German outfit Bayer Leverkusen last summer whilst 26-year-old Willian joined for around £30 million a couple of months later from Russian club Anzhi Makhachkala.
Both took a couple of games to get used to the Premier league but soon found their feet in arguably the best league in world football.
Although he gets a decent tally of goals for a wide player, Schurrle is guilty of missing the odd easy chance when his side need a goal.
Willian, on the other hand, is effective in almost every game he plays in, with his lack of goals giving Schurrle an edge.
However, with striker Diego Costa setting the world alight in his first seven Premier league games, firing an exceptional tally of nine goals, it appears that is not the problem for Chelsea anymore.
So who does Mourinho opt for?
It really is too close to call. Whilst Schurrle is a more natural goalscorer, Willian makes up for it in his tireless work rate and consistent performances.
It looks like the Chelsea boss has a dilemma on his hands as both are fantastic players.
