West Ham United have announced the signing of Borussia Monchengladbach midfielder Havard Nordtveit.

Nordtveit, 25, signs on a five-year deal and returns to London six years after leaving Arsenal to join Monchengladbach.

He told the Official Website: "It has always been a dream for me to play in the Premier League and now I have a big opportunity to do that for West Ham – I cannot wait to start!

"This team has something special, a spirit in the team that I can fit into. I will work hard and hopefully I can get some good moments at this Club.

"I'm a player who can play many roles on the pitch, but I'm from Norway so maybe a little bit more running, tackles and try to spread a few balls around me.

"I'm looking forward to showing what I can do, but hopefully I have something to help West Ham achieve even more."
