Arsenal are to receive £3 million as part of Thomas Vermaelen's transfer to Barcelona if the Liga club win the Champions League, according to newspaper reports.

Vermaelen, 29, signed for Barcelona for £15 million last summer but injury problems have meant he has yet to make a single appearance for Luis Enrique's side.

However, an agreement in the terms of his move to the Camp Nou means that should Barca lift the Champions League trophy against Juventus on June 6 then Arsenal will benefit financially.
