Welbeck, Chambers, Ospina, Debuchy: Four new Arsenal signings are yet to prove their worth

Arsene Wenger Waves

Arsenal's 2014/15 summer signings need to step up next season, to show Alexis Sanchez wasn't the only success from the group.

Alexis Sanchez has been a roaring success at Arsenal since signing last summer, voted this week as the PFA Fans Player of the Year, reported The Guardian.

There was never really a doubt that the talented Chilean would thrive in the Premier League after his switch from Barcelona, considering his worth ethic, pace and supreme technical talent.

He was not the only new signing Arsenal made last summer, and a trio who arrived alongside him are yet to fully convince despite having their moments.

While Sanchez is a certain 'hit', Danny Welbeck, Calum Chambers, Mathieu Debuchy and David Ospina are not 'misses', but remain 'maybe's', heading into their second season with the club, with it all to prove.

Here is a look at what has gone right and wrong for each player...

Danny Welbeck

Welbeck arrived in a late deadline day deal from Manchester United, and was talked up as being the next great Arsenal striker. He started well, bagging a hat-trick against Galatasaray in the Champions League, but they landed up being the only goals he scored in the competition. In the Premier League he failed to dislodge Olivier Giroud from the striker's spot after the Frenchman returned from injury, and had to make do with a place on the bench, or on the wing. His figures of four goals in 25 league games is woeful, but his winner against former club Manchester United in the FA Cup is a memory to savour.

David Ospina

Colombian goalkeeper David Ospina appeared to have slipped to third choice early in the season after Emiliano Martinez broke through. He ended up as the undisputed number one after seizing his chance and displacing gaffe-prone Wojciech Szczesny. He is still to wholly convince however, and nearly conceded a howler against West Brom at the weekend.  ESPN report Arsenal are interested in Petr Cech, which underlines Ospina still has work to do whether they sign the Chelsea goalkeeper or not.

Calum Chambers

Former Southampton defender Calum Chambers played an important role early in the season, featuring more frequently than Arsene Wenger would have liked due to injuries. There were solid performances from the England under-21 international, but the memory of him being turned inside out by Swansea City winger Jefferson Montero was an enduring one as Arsenal lost at the Liberty Stadium in the Autumn. He lost the right-back spot to Hector Bellerin when it was there for the taking, and has made just two starts since March began. It remains unclear whether his best position is right-back, centre-back or defensive midfield, and Chambers needs to hold one down to avoid being regarded as a Phil-Jones type utility man.

Mathieu Debuchy

Mathieu Debuchy's debut season at Arsenal has been wrecked by two serious injuries, and it is hard to judge him accordingly. Looking forward, his time out of the side has posed a question mark over the position which was not there before, with Hector Bellerin highly impressive in his absence. The Spaniard is going nowhere either, and is currently keeping Debuchy out of the side despite him being fully fit, and next season he needs to make his experience count by seeing off his more junior rival, staying fit, and getting a run in the side of his own.
