London - Swansea signed Hull midfielder Sam Clucas for a reported £15 million on Wednesday.
Clucas agreed a four-year contract with the Premier League club and is expected to step into the role played by Gylfi Sigurdsson before the Iceland international moved to Everton last week.
The 26-year-old is Swansea manager Paul Clement's first signing since Sigurdsson's £45 million transfer.
Clucas shone for Hull last season despite their relegation from the top-flight and appeared three times in the Championship this season before missing last weekend's match against QPR as speculation mounted about his future.
After being released by Leicester as youngster, Clucas revived his career with a spell at the Glenn Hoddle Academy.
He played for Mansfield and Chesterfield before joining Hull in 2015.
Clucas could make his Swansea debut in Saturday's Premier League clash at Crystal Palace.
