Twitter Reacts as Juan Mata's Red Card Costs Dreadful Manchester United Dear

And so the Manchester United renaissance is over. 

Louis van Gaal's side's good run of form came to an end as they crashed to a 1-0 defeat at West Bromwich Albion on Sunday. 

They were skating on thin ice as soon as Juan Mata was sent off in the first half. 

"

I've seen lazy challenges, dumb challenges, and dirty challenges. I've never before seen a challenge that maxed out all three.

Juan Mata.

United went into the game full of optimism, and there was even talk they had ended their reported interest in Jose Mourinho.

But when striker Salomon Rondon gave the Baggies the lead, the mood on social media quickly changed. 

"

If this team was managed by SAF they would be winning regardless of the sending off, he would be on the touchline, LvG sits there for 90min.

"

Varela and Memphis should have started the game along with Schniderlin. Lvg is an absolute waste of time as a manager.

Good luck, Louis. You're going to need it.
