When Manchester United face up against Olympiacos in their Champions League tie they may be facing up to a future foe for the first time.
Young Costa Rican Joel Campbell has been one of the standout performers for the Greek side this season and could well be doing the same for Arsenal next season.
Arsene Wenger signed the promising striker from his native Costa Rica in 2011 and immediately loaned him to FC Lorient where he failed to get going. A loan to Real Betis followed that next season and he started to show signs of promise.
In the summer of 2012, Campbell qualified for a work permit but Wenger still opted to send him on loan, this time to the sunny climes of Greece and their most dominant side.
He has since turned into a key performer for the team, scoring seven goals and assisting 10 from a wide position.
With goal machine Kostas Mitroglou no longer at the club, Campbell will now play an even more important role in the team towards the end of the season.
But despite his impressive form, there has been no word on his future at Arsenal. Wenger has not spoken of the Costa Rican this season and it seems more likely that the 21-year-old will leave on another loan spell or maybe even permanently in the summer.
That could all change against Manchester United, however. Scoring and assisting freely in the Greek league is one thing but performing against the current Premier League champions is quite another.
David Moyes' men will stand as the biggest challenge the player has faced so far this season. Perform well and Wenger will have to choice but to sit up and take notice. If he fails to impress then Wenger will be more convinced than ever that Campbell won't be able to perform in the Premier League.
Olympiacos go into the round of 16 tie against Manchester United as heavy underdogs and no one would expect to see the Greek league leaders in the last eight. But that doesn't mean Campbell can't show off his talent in vain.
With the British football community watching on, Campbell has a chance to get his name in the papers and get Wenger thinking about where he will fit him into the set up.
How Campbell performs in Athens and on the return leg at Old Trafford could well decide his future at Arsenal altogether.
