Manchester United striker Zlatan Ibrahimovic has reiterated his belief that Jose Mourinho is a "mastermind" and revealed his only regret is that he didn't have more time to play under the Portuguese boss.
Ibrahimovic and Mourinho spent a year together at Inter Milan, where the United boss led the club a historic Treble of Serie A, Coppa Italia and Champions League titles the season after selling the Swede to Pep Guardiola's Barcelona.
The two stars have reunited at Manchester United, where they will participate in their first Manchester derby on Saturday against Guardiola's City. And the former PSG man hailed Mourinho ahead of the match.
"Mourinho is a mastermind. He knows everything about the game," Ibrahimovic said.
"I do not have many regrets, but I do regret that I did not get to play under Mourinho for longer. When the opportunity came again for him to be my coach at United it was an easy decision.
"Who wouldn't want to be coached by him? I am at a great club with a great coach and great fans and I want to be as successful as possible for them."
Ibrahimovic has helped United to a 100 percent Premier League record thus far -- matching City's impressive start to season -- making this campaign's first derby between the two even more special than usual.
"These games always mean so much to the fans and we want to win for them, but the players must always be focused," Ibrahimovic said.
"Every game must be looked at as an opportunity to win three points whoever the opposition."
On the absence of City striker Sergio Aguero through suspension, Ibrahimovic said: 'You know when you play the teams at the top that any team they put out is going to be dangerous."
