Watford have made it two signings in as many days with the arrival of midfielder Prince Buaben on a free transfer.

The Ghanaian has signed a two-year contract after his contract with Dundee United expired this summer.

The midfielder joined Ajax as a 15 year old but due to residency rules was unable to sign a professional contract with the club when it was offered.

So Buaben moved to England and was playing non-league football when he was spotted by Dundee United boss - and now Scotland manager - Craig Levein, who signed him in 2007.

The 23-year-old made almost 150 appearances in his four years at the club, scoring 11 goals, and was part of the Scottish Cup winning side in 2010.
