Manchester United goalkeeper David De Gea feels Chelsea will find Barcelona too strong in their Champions League semi.

De Gea is impressed by Chelsea, but says Barca are a step above.

"Chelsea are a very strong team but they will find it very difficult because if Barcelona play at their usual level, the tie will be theirs," said De Gea, before praising Chelsea's Spaniards.

"Juan Mata and Fernando Torres are both having very good campaigns."
