Former Athletic Bilbao coach Howard Kendall has warned Manchester United ahead of tonight's Europa League clash.

Kendall, who led Everton to a league title, also has experience managing Bilbao.

He told the Daily Mail: "The game should be some tie. Javi Martinez is brilliant and Fernando Llorente is like a typical English centre forward, a real physical threat. United have to try to cut off the service to him. But it's not just those two that make me think United will need a decent lead for the second leg.

"They may need a couple of goals, because they will wonder what has hit them over there. It's only 40,000, but they make a noise like nowhere else."
