There’s nothing quite getting a win over your biggest rivals.Manchester City claimed a 3-1 victory against Manchester United at the Etihad on Sunday, hoisting them back to the top of the Premier League in time for the international break.David Silva broke the deadlock 12 minutes in to kick-start what proved to be relatively comfortable afternoon for the reigning champions.Sergio Aguero and Ilkay Gundogan scored City’s second and third either side of an Anthony Martial goal, wrapping up their seventh win on the trot in all competitions.Perhaps rather typically, Jose Mourinho felt the scoreline wasn’t a true reflection of the performance his team produced in their third consecutive outing away from Old Trafford."It's a heavy result for the effort of a team that had three away matches in the same week, with a super difficult match of a high, demanding level in Juventus against a team that had two friendly matches at home against Southampton and Shakhtar," he told BBC Radio 5 Live."The physical fatigue and the mental fatigue leads to mistakes. They were tired physically and mentally. You need to be in football or another high-level sport to know what that is. The concentration of the big matches, they dry you. You are dry inside. To be ready again for another big match is not easy.”Well, it’s safe to say Pep Guardiola and his men won’t have much sympathy for the Red Devils and their fixture schedule.City completely outplayed their crosstown rivals - so much so that Kyle Walker couldn’t resist rubbing salt into their wounds on social media.

KYLE WALKER'S DELETED TWEET

His tweet, which was deleted shortly after it was posted, read:

“Our opponent was red. We heard the away fans boo.

“We’re twelve points ahead. And just like violets, Manchester is blue.”

WALKER'S FOLLOW-UP TWEET

Now, Walker has followed up with another message to explain the thought process behind his initial one - and it’s quite funny.

The new tweet reads: “*Wins Manchester Derby*.

“My brain: don’t tweet it, don’t tweet it, don’t tweet it.

“Don’t tweet it, don’t tweet it, don’t tweet it, don’t tweet it, don’t tweet it.

“Me: the opponent was red…”

It just goes to show, mocking isn’t always the best way to get a laugh on social media.

Walker appears to have learnt his lesson, but considering how easily he succumbed to the temptation of taking a pop at United, a repeat performance could well be on the cards.
