Ahead of Manchester United’s game against Arsenal, David de Gea has sung the praises of Petr Cech, who joined the north London club from Chelsea this summer.

Arsenal lost their second Champions League game earlier this week, as Olympiacos won their first game on British soil in their 3-2 win at the Emirates.

Petr Cech was rested for the game and his replacement, David Ospina, was guilty of a dreadful mistake, dropping a simple catch over the line, to put Arsenal 2-1 behind.

I think he is a great keeper, one of the best in the world. 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.
