Zlatan Ibrahimovic says there's no big secret to his success.

The big Swede will make his Manchester United debut this weekend against Galatasaray.

Ibrahimovic touched upon his personal philosophy that has served him so well as he approaches his 35th birthday in October.

"I believe in working hard," he stressed to MUTV.

"Not only in games but even in training. The way you train is the way you play in the games - that's my philosophy. Working hard, training hard and feeling good. Then you need to get the rhythm by playing games."
