Manchester United are busy preparing for their Europa League clash against Fenerbahce at Old Trafford on Thursday and Luke Shaw revealed who he thinks could cause a problem in his pre-match press conference.

Shaw revealed that Robin van Persie will be the main threat as far as United are concerned due to his quality and for the fact he knows the club well having previously played there.

The England international did not however, underestimate the rest of the Fenerbahce side and underlined that United will be focusing on the entire team.

Van Persie spent three seasons at United, lifting the league title and scoring 58 goals.

Fenerbahce are currently first in Group A on four points but a United victory would take them into pole position on six points.
