Mourinho has reportedly agreed a three-year contract worth £60 million, reports Toby Gannon of ‘the Sun’.
However, negotiations over his image rights are ongoing and must be concluded before his arrival is announced, says Andy Burton of ‘Sky Sports’.
BBC Sport had reported on May 21 that United will soon officially announce Mourinho as the club’s manager.
The Portuguese is taking over from Louis van Gaal, who was sacked as United manager, two days after wining the FA Cup – the Red Devils first since 2004.
