The former Tottenham striker joked about the Manchester United boss's decision to use a surprise striker.
Indeed, Manchester United lost 3-0 at White Hart Lane on Sunday.
And Van Gaal decided to introduce Ashley Young as a centre-forward, moving Anthony Martial out wide...

Sometimes you just have to wonder about Van Gaal. Is the Manchester United boss making decisions simply to be different - and with no real logic?
On Sunday, Spurs showed United that, no matter how much Van Gaal talks about the Old Trafford outfit being a bigger club, there is no doubt which is the better side at the moment.
Tottenham are a full 12 points ahead of Manchester United but the true gulf in class is even greater than that.
Can Van Gaal survive at Man United until next season? Or will his bizarre changes and poor overall management be the end of him in Manchester?
