United just decided to grind out the end of that game. Johnson should've gone for the rugby tackle though which would've made it easier.
Valencia fouled him before the tap tackle, had Valencia not pulled him back to get past I'd agree though, silly from Johnson to even do it, he was covered.
Thankfully not filled with controversy, a lucky deflected goal to win it, can't be too disappointed considering should've been 4-0 at half time, if Rooney was on we would've been tanked with Allen on.
