LONDON (REUTERS) - Jose Mourinho has agreed personal terms to become manager of Manchester United, Sky Sports television reported on Tuesday quoting unnamed sources.

The 53-year-old Portuguese is set to replace Dutchman Louis van Gaal whose two-year reign at Old Trafford was ended on Monday, two days after United lifted the FA Cup.

The self-styled "Special One", Mourinho was sacked by Chelsea in December, ending his second spell in charge of the London club.

He has also managed Porto, Inter Milan and Real Madrid.

Earlier, British media reported that Mourinho's agent Jorge Mendes flew into London on Tuesday to lead the discussions with United.

Mourinho was fired by Chelsea seven months after winning his third Premier League title for the Stamford Bridge outfit.

He has been consistently linked with the United job this year, with Van Gaal's team eventually finishing fifth in the Premier League and failing to qualify for the Champions League.
