Watford have confirmed the signing of Swedish international midfielder Ken Sema from Ostersunds.

The 24-year-old has signed a five-year contract after moving to Vicarage Road for an undisclosed fee.

Sema becomes the Hornets' fifth signing of the summer so far following the arrival of Ben Wilmot, Gerard Deulofeu, Marc Navarro and Adam Masina.

His move was announced by his former club yesterday and chairman Daniel Kindberg said in a statement: “Ken Sema is a great person both on and off the pitch. I am very happy for him and the whole club wants to congratulate him. At the same time, he will of course be missed."

Perhaps best known in this country for scoring to help Ostersunds to their memorable 2-1 Europa League triumph at Arsenal last season, the attacking midfielder made a total of 84 appearances in two-and-a-half years with the Swedish top-flight club.
