This Manchester united star could leave the club at the end this summer

The Spaniard international and Manchester united skipper, Juan mata, could possibly leave the club at the end of this summer. Manchester united signed the player from rival club, Chelsea, in 2014 on a four and a half years deal which will end in this summer.
Manchester united had a 12months extension clause in a deal that brought the Spaniard to old Trafford, but they yet to activate the extension year for the player, which could lead the player leave the club on a free transfer.
However, Inter Milan or former club Valencia could possibly sign the player at the end of the summer, if Manchester united fails to activate the 12months extension clause.
