Norwegian defender Omar Elabdellaoui is rejoining his former club boss Marco Silva at Premier League strugglers Hull City on loan from Olympiakos.
The Greek side, who were managed by Silva until June last year, confirmed the move on their website on Friday.
Hull, 18th in the Premier League and level on points with 17th-placed Crystal Palace, announced earlier that midfielder Jake Livermore was joining rivals West Bromwich Albion on a four-and-a-half-year deal for £10million.
'It is never good when we lose an important player, but it was a good proposal for the player and the club,' Silva said.
