Ahead of their Barcelona clash on Tuesday 16th April, Manchester United goalkeeper David de Gea has issued a warning to his teammates that they must improve if they are to secure a semi-finals place in the Champions League.

United struggled to beat West Ham United over the weekend after another lethargic performance and needed penalties from Paul Pogba to help them to a 2-1 victory. Key saves from de Gea kept them in the West Ham clash as the visitors struck the woodwork in the second half through Michael Antonio. The Red Devils are 1-0 down after the quarter-final first leg to Barcelona and need to win when they travel to the Camp Nou to progress to the next round. 

The Spanish shot-stopper noted that United will have to bring their A game if they are to beat Barcelona, "Of course it's difficult, but if you want to be a top team you have to play big Champions League games, and the weekend after it's the Premier League. So you have to be focused and ready for a difficult game again. I think today we didn't play well, we have to improve a lot and now we have a big challenge on Tuesday.

“It's a big challenge, a special occasion, in Spain, against Barcelona, a Champions League night, so it's going to be an amazing game. We're happy with the win, but at the same time we have to improve a lot.”
