Man United's Zlatan Ibrahimovic still motivated by Pep Guardiola clash
Manchester United striker Zlatan Ibrahimovic has said he still gets "adrenaline" from his falling out with Pep Guardiola at Barcelona.
Guardiola brought Ibrahimovic to the Camp Nou in 2009 but the relationship between the pair broke down and he was loaned to AC Milan after only a season before making the move permanent.
The striker has been outspoken in his criticism of Guardiola since and, when Manchester United face the coach's Manchester City next month, Ibrahimovic will be fired up.
In an interview with former England coach Fabio Capello on Fox Sports Italia, he said: "I learned from Barcelona, both on and off the pitch. I learned that in football any situation can change in 24 hours.
"The problem wasn't with me, it was with him, and he never came to terms with it. I don't know what his problem was with me.
"It is something that drives me, gives me adrenaline and extra motivation. It is normal after what has happened. I'm using it as a positive, not negative."
United travel to the Etihad Stadium on April 27 for what could potentially be a decisive clash in the battle for a top four place.
But former United boss Sir Alex Ferguson believes the club should prioritise winning the Europa League to secure a Champions League place.
United are favourites to win the one major European title they have never claimed and take on Anderlecht in the quarterfinals.
Ferguson told ESPN FC: "The thing is, we've never won the Europa League. We've never won [the] UEFA Cup, which is what it used to be.
"And we've got a great draw. I'm not saying it's a certainty, but they've got a great chance.
"If you win a trophy, it's important. It doesn't matter that it's not the Champions League -- it's still a European trophy.
"And if you win it, you get into the Champions League. The incentive is greater to do that."
