Manchester United midfielder Juan Mata is happy for Victor Valdes after he made his debut in their 1-1 draw against Arsenal.

David de Gea injured his hamstring during United's 1-1 draw with Arsenal yesterday and was replaced by former Barcelona stopper Valdes.

Mata wrote on his blog: "We had more bad news when David had to leave the pitch with an injury, which allowed Victor to make his debut as a Manchester United player.

"I hope David gets well soon and at the same time I wish Victor the best, always.

"A goalkeeper like him, so good and with so much experience, is always a big help to any team."
