Arsenal are preparing summer moves for three world class players to bring Arsenal back into the mix to challenge for the title, according to the Mirror.

The Gunners have spent more than £100m over the past two seasons, mostly down to the acquisition of Mesut Ozil for £42m and Alexis Sanchez for a fee in the range of £30m.

However, the lack of a top keeper and injuries to key players at crucial points in midfield has left a gaping hole in the team which Arsene Wenger is willing to rectify this summer.

The Gunners are looking at Petr Cech to alleviate their goalkeeping crisis, with Wojciech Szczesny far from being the dependable figure he can be this season.

The Pole fumbled the ball on occasions and his distribution got the Arsenal defence into trouble on multiple occasions against Manchester United at Old Trafford, which otherwise could have been a much easier night for the Gunners.

David Ospina is doing well between the sticks but the Colombian does not emanate much confidence owing to his handling of the ball and the Gunners, looking to challenge for the title, can do better in that respect.

However, it is down to Jose Mourinho if he wants to sell Cech to his nearest rivals, having previously prevented the likes of Demba Ba from making the move to the Emirates.

Wenger is also reported to be preparing a move for Southampton midfielder Morgan Schneiderlin to provide cover in defensive midfield for Francis Coquelin and also play alongside him.

The Frenchman has been in brilliant form this season and can put in a shift in the absence of Aaron Ramsey and Jack Wilshere who have been vastly anonymous this season, owing to injuries.

The departure of Mathieu Flamini and the uncertain future plaguing Mikel Arteta, a central midfielder, is high on Wenger's list in the summer.

Arsenal scouts also watched Borussia Dortmund defender Neven Subotic last weekend and are mulling over making a bid for the player as a long term replacement for Per Mertesacker, whose form over the length of the season has failed to inspire any confidence.
