Arsenal are interested in signing Chelsea playmaker Juan Mata this summer.

The Spaniard's future at Stamford Bridge has been under scrutiny since Jose Mourinho's return as manager.

And Sportsmail understands the Gunners are being kept updated with regards to the former Valencia man's future with a view to launching an audacious swoop should Chelsea decide to sell.

Manager Arsene Wenger came close to landing Mata in 2011, but Chelsea pipped the Gunners to the 25-year-old.

Mata has become one of the Premier League's best ever imports, winning the Champions League, Europa League and FA Cup since his arrival.

Chelsea insist the player is not for sale this summer, but Arsenal will continue to watch the situation carefully should their stance change.
