Arsenal face a huge battle this summer as they seek to build upon what has been a disappointing season at the Emirates Stadium.
The Gunners have struggled for form across all competitions and now have all of their eggs firmly in the Europa League basket, which now stands as their only realistic route back into the Champions League.
The north London side will hope to keep their core squad intact and look to sign additional depth to bolster themselves in key areas but the Gunners risk losing key members of their squad in the transfer market, as a wealth of links are emerging in the press.
The Manchester Evening News states that a source close to Manchester United has stated that the Red Devils are keeping tabs on 22-year-old Spanish international Hector Bellerin, widely linked with an exit from the club.
United are in the market for a long-term replace for Antonio Valencia, who turns 33 this year, but will have to part with an astronomical fee to lure Bellerin to Old Trafford.
