Benfica are prepared to sell Nicolas Gaitan when the window reopens.

The Argentine international has enjoyed a fine season for the Portuguese giants, including helping them knock Manchester United out of the UEFA Champions League.

Reports suggest the Estado de la Luz club are prepared to sell Gaitan for £25million in the summer, but United could face competition from rivals City for the forward.
