West Ham have re-signed George McCartney on a season-long loan from Sunderland to become Sam Allardyce's sixth summer signing.
McCartney first joined the Hammers in August 2006 following a £1million switch from the Black Cats and he went on to make 71 appearances during a two-year spell.
The 30-year-old spent most of last season in the Championship on loan at Leeds United, a side which he could now line up against on Sunday week.
McCartney is delighted to be back at Upton Park having enjoyed his first spell with the East London outfit and he is eager to help the team win promotion back to the Premier League at the first time of asking.
"It is brilliant to be coming back. For me personally it will be great to be playing again for a club like West Ham," he told the club's official website.
"It is a big opportunity for me and I can't wait to get started again. I am looking forward to being part of the manager's squad and the club's push for promotion.
"I have got experience of the Championship. It is a tough league to be in but with the signings the manager has made already and the players already here, it is a healthy squad. In my eyes, it is more than capable of getting us up at the first attempt.
"The West Ham fans are fantastic. I remember how good they were to me when I was here before.
"I know that if you do the business on the pitch, they will get behind you both home and away. More than ever this season, we need them behind the team as we look to try again promoted. The fans will be a big part in that."
