Nigerian striker Isaac Success has completed his transfer to Watford for a club record fee.

After penning a farewell letter to former club Granada yesterday, Success' move to Vicarage Road has now been confirmed to complete a busy day of transfer activity for the club.

After finalising the signing of Christian Kabasele and a new five-year deal for star striker Troy Deeney, Watford have moved to make their third significant announcement of the day with the capture of the 20-year-old, for a fee around the €9 million to €11m figures which have been reported previously, although it has been claimed the price could be as high as £12.5m.

Success was linked with moves to Paris Saint-Germain and Inter Milan, but has instead committed himself to a five-year contract with Walter Mazzarri's side.
