West Ham have confirmed the capture of Liverpool winger Stewart Downing in a deal that could potentially be worth around £5.5million.

It is believed the Hammers have paid an initial fee of £1.5million plus an extra £4million in performance based add-ons.

Downing joins the Hammers following two frustrating years at Anfield following his £20million move from Aston Villa in 2011. The 29-year-old England international went on to make 65 Premier League appearances for the Reds, scoring three goals.

Downing, who has signed a four-year contract, told “I’m very excited. It’s a great opportunity for me being here. It’s a great club and I can’t wait to get going.

“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.

“It’s all happened quickly, but I’m really excited and hoping to play a part on Saturday.”

The former Middlesbrough and Aston Villa player has been capped 34 times by England.

Downing will wear the No.23 shirt for the Hammers.
