Jose Mourinho says there is only one person to blame for Juan Mata being made surplus to requirements at Chelsea and that is the midfielder himself.
Speaking ahead of the Blues' FA Cup fourth round tie with Stoke City on Sunday, Mourinho was asked about the imminent £37million transfer of the forward to Premier League champions Manchester United
The Chelsea manager was also quizzed on what he thought about the significance amount of fans and football commentators questioning the wisdom of allowing Mata to go to a rival club, even if this season David Moyes' side are unlikely to trouble the title race.
Mourinho was adamant Mata's lack of playing time was down to the 25-year-old's inability to adapt to the Portuguese's demands and suggested he was "not clever" enough to make himself a success in the new regime.
"For my players, if they go the only reason for is they are not playing. If they go, it’s because they are not clever," he is quoted as saying by the Daily Express.
Mata will now link up with the likes of Robin van Persie and Wayne Rooney at Old Trafford, with manager Moyes hoping the Spain international can help to fill the creative gap in the side that has been evident in this difficult season so far.
Meanwhile, Chelsea are reportedly close to spending some of the Mata money already, with the £11million signing of Liverpool target Mohamed Salah from Basel expected to be finalised soon.
