Chelsea and Arsenal are both in the hunt for out-of-favour Southampton goalkeeper Fraser Forster.
The 32-year-old has been on loan at Celtic this season, and the Scottish club are also interested in signing him permanently.
However, the Premiership champions could face some competition from London as Chelsea are 'assessing the keeper amid doubts over his future at St Mary’s Stadium', according to Football Insider.
There are suggestions that Chelsea boss Frank Lampard is looking to sell current number one Kepa Arrizabalaga after several high-profile blunders between the sticks this season.
