Arsenal boss Arsene Wenger has revealed Fran Merida has agreed a new deal, but has yet to sign it.

Merida's future has been the subject of speculation in recent weeks with Atletico Madrid keen to take him back to Spain.

The 19-year-old's current contract expires next summer and Arsenal are keen to tie him down to a new long-term deal.

However Wenger admits other clubs have been undermining their attempts to agree a new contract with Merida - and the Frenchman is not happy with the way Atletico Madrid have made their interest known.

"He has an offer which he has agreed, but has not signed yet," said Wenger.

"Some clubs are doing their work behind our back to destabilise him.

"We cannot stop that, but it is a fact."
