Ben Foster and Ken Sema sign for Watford

Foster spent seven years playing for West Brom

Watford have signed West Brom goalkeeper Ben Foster on a two-year deal.

Foster returns to Vicarage Road having spent two years on loan with the Hornets during his time with Manchester United.

The 35-year-old made 223 appearances for West Brom during a seven-year spell with the Baggies.

He becomes Watford's second signing of the day after winger Ken Sema joined from Ostersund.

The fee for either player has not been disclosed.

Watford have the option to extend Foster's contract by an additional year.

Foster and former West Brom team-mate Craig Dawson were fined by the club for refusing to go on a pre-season tour amid interest from other clubs.

Meanwhile, 24-year-old Sweden international Sema has agreed a five-year deal with the Premier League club.

Sema has been capped five times by his country but is not part of the World Cup squad that will meet England in Saturday's quarter-final.

He scored the winner for Ostersund against Arsenal at the Emirates last season as the Swedish side reached the last 32 of the Europa League.

The Swedish minnows - they were playing in the fourth tier with gates of fewer than 500 in 2010 - lost on aggregate to Arsenal but became one of the stories of the competition as they knocked out established European giants such as Galatasaray of Turkey and Bundesliga side Hertha Berlin.

"Ken Sema is a great person. I am very happy for him and the whole club wants to congratulate him. At the same time, he will of course be missed," Ostersund chairman Daniel Kindberg said.
