Richards said: "Obviously it is nice to get back after so long but it is nice to get a clean sheet.

"But I thought James Milner was my man of the match. I thought he was outstanding, he was everywhere.
"Obviously Kolarov had a good game as well, so it was an all-round good team performance and I am just happy to be back."
