Michael Bradley has completed his loan switch to Aston Villa from Borussia Monchengladbach.
The United States international will now see out the 2010/11 campaign at Villa Park, with the option for the move to be made permanent in the summer.
He is still waiting on international clearance and for a visa to be granted, but the 23-year-old is delighted to have arrived in the Premier League.
"I am really excited to be joining Villa," Bradley told the club's official website.
"I am proud and thrilled and can't wait to get going now.
"Everyone can see that Villa is a big club, a fantastic club, with tradition and great supporters. Over the past few years Villa have made big strides and are trying to challenge at the very top of the Premier League. I am excited to be part of that.
"I want to play at the highest level and test myself in the biggest of games. Whether it's on Saturday against Fulham at Villa Park or the week after, I am excited to be here and ready to get going."
Bradley added: "For me, the Premier League is the best league in the world. To have the opportunity to come here and test myself at the highest level week in, week out, is incredible and try to take the things I do as a player and make them count at the highest level - it's a great challenge."
Villa boss Gerard Houllier is pleased to have added to his ranks on deadline day, with Bradley having been identified as a target for some time.
He said: "Michael is 23 and is a very hard-working midfielder who can score goals and is versatile.
"I saw him play four times in the World Cup last summer so, in terms of scouting, you cannot say the work has not been done because I saw him just a few months ago.
"We are very happy to have him. Despite his age he is an experienced player. He will add to the squad and he will bring energy and legs in midfield when we need it."
