Jose Mourinho proved his loyalty to new club Manchester United by refusing to sign a Chelsea shirt for a fan.

The Portuguese manager and his team are currently on a preseason tour in China and stopped to sign autographs and memorabilia for waiting fans.

Mourinho walked the length of the crowd quickly signing red jerseys but waved away a Chelsea jersey with a shake of his head.

Check out the cheeky smirk as he said no.

We’re willing to bet he was secretly tempted to sign it, just for the brouhaha it would cause.
