Manchester United have parted company with Manucho after the Angola international agreed a five-year deal with Real Valladolid.
The 26-year-old moved to Old Trafford last year but made only three substitute appearances for Sir Alex Ferguson's team.
Before his stint with United, Manucho was the leading scorer in Angola's top division, netting 16 goals in the 2006-07 campaign and 15 the following season.
He had a spell on loan with Panathinaikos towards the end of the 2007-08 season and joined Hull City for a temporary spell last term.
He started eight matches for the Tigers and made nine further appearances from the substitute's bench but only found the net twice.
