Erstwhile Chelsea playmaker Juan Mata, who recently secured a £37m transfer to Manchester United, was deemed surplus to requirements at Stamford Bridge.
Rather than rejoice in the remuneration received from the big-money deal, Blues boss Jose Mourinho has indicated that he regards the foundations of Mata's departure to be a personal failure on his part, something he has apologised for, as he alludes to the fact that the Spaniard did not receive as much pitch-time as Oscar or Eden Hazard as his performances did not match the attack-minded Brazilian or the technically-adept Belgian.
'I am sorry that I didn't make him a stronger player,' Mourinho lamented on Sky Sports.
'Maybe it was something new for him, not to be first choice in a difficult moment,' he continued. 'Maybe that made him, as a man, as a player, stronger but I gave him nothing to be honest and I feel sorry with that.
'I tried to make him play in a position where he was not comfortable. He gave everything and played some good matches in that position. We are speaking about a world champion, a European champion. It is difficult for him.
'I feel sorry for that and because of that I feel we couldn't stop him going to Manchester United, despite being Manchester United's direct rival.'
