West Ham have confirmed the signing of England international Stewart Downing from Liverpool for an undisclosed fee.
Downing has agreed a four-year deal with the Hammers and he follows Andy Carroll in making a permanent move from Anfield to Upton Park this summer.
The 29-year-old midfielder, who has won 34 caps for England, is West Ham's fifth new recruit of the summer.
"I'm very excited," said Downing, who is predominantly a left winger but spent a lot of time playing at left back for Liverpool last season.
He added on West Ham's official website: "It's a great opportunity for me being here, it's a great club and I'm really excited to get going."
Downing is ready to compete for a place in the West Ham side to face Cardiff on Saturday on the opening weekend of the Barclays Premier League season.
He said: "I'm ready and I'm fit for the first game against Cardiff City.
“I've played a decent few games for Liverpool in pre-season, so there will be no problems on that front."
Liverpool have taken a significant loss in selling Downing and Carroll to West Ham for a combined fee reported to be around £21million.
Kenny Dalglish signed both players for Liverpool in 2011, with Carroll reported to have cost £35million from Newcastle and Downing £20million from Aston Villa.
But neither featured in Brendan Rogers' long-term plans and Downing was told last autumn that he could leave the club.
Downing responded by forcing his way back into the Liverpool first team and he made a total of 45 appearances last season, featuring both on the left wing and at left back.
Andy Carroll welcomed Downing's signing for West Ham on Twitter.
