Manchester United goalkeeper David de Gea has great respect for Arsenal's Petr Cech.

Although left out of the shock Champions League defeat to Olympiacos in midweek, the veteran is expected to return to the line-up at the Emirates Stadium this weekend.

"I think he [Cech] is a great keeper, one of the best in the world," De Gea told MUTV. "I think that having him in goal will really help Arsenal a lot. He's got so many games under his belt and he's just a top, top goalkeeper.

"That's a decision for the coaches [resting Cech on Tuesday]. At the end of the day, he wants to give both his keepers some playing time and obviously David Ospina is a good keeper who can also perform well for them.

"Arsenal are one of the best teams in the Premier League. They have some very good individuals, very fast players up front and I think they are a very good side. Even though they lost at home, they'll be really up for it on Sunday and will want to give their fans something to cheer about, so I think they'll make it very tough for us.

"We'll go there full of confidence, we know it's in our hands to stay at the top [of the table] and we'll go there believing in ourselves and all out for the three points."
