It seems fashionable to mock any signing that rival clubs make.No matter who it is, rivals fans will always try and focus on any negative that player may have.We’ve certainly seen that as far as Romelu Lukaku is concerned.Everyone is pointing at his questionable first touch and believe he isn’t worth the £75 million Manchester United have paid for him.But United fans are trying to hit back.With Chelsea seemingly missing out on Lukaku and signing Alvaro Morata instead, United fans have been taunting them.But what about Arsenal’s Alexandre Lacazette?With him playing in France his entire career for Lyon, Premier League fans may not know too much about him.But it hasn’t taken them long to start mocking him after his performance against Chelsea in a pre-season friendly.Now, as mentioned, a lot has been made of Lukaku’s first touch. Therefore, United fans would have been analysing Lacazette to see any signs of weakness - and they might have found it.It seems Lacazette’s first touch also needs some work.

Watch: United fans mock Lacazette's touch

A United fan uploaded a video of his terrible touch against Chelsea with the caption: “I do not want to hear any Arsenal fan talking about Lukaku's first touch ever again.”

United fans react on Twitter

And this is how United fans reacted to the awful moment from the striker:

In truth, it is a rather terrible touch from Arsenal’s record signing.

But they weren't finished there. Another United fan tweeted yet another video of Lacazette messing up his touch by accidentally nutmegging himself.

Take a look:

The war between the forwards is very much on.

The only way both Lukaku and Lacazette can silence their haters is by scoring goals.
