Queens Park Rangers midfielder Joey Barton has admitted that he is "gutted" by Steve McClaren's appointment as Derby County manager.
The 52-year-old was named Derby's new boss on Monday evening following a three-month spell as a coach at QPR.
Barton tweeted: "Gutted Steve McClaren has left for Derby. Top coach. Big loss for us. Wish him all the best at a great football club."
McClaren has signed a two-and-a-half-year contract at Pride Park.
