Two goals deep into second half stoppage time helped seal the mother of all dramatic wins over . The Red Devils came from two goals down to lead 3-2, but the Blues struck twice late on to take all three points, with ex-Manchester City man Cole Palmer netting a stunning hattrick. The win, which is Chelsea's first over United in 13 attempts in the , will have done wonders for Mauricio Pochettino's chances of remaining in the Stamford Bridge hotseat. Despite that, there were plenty of things he got wrong tonight, and a couple of things he got right. Here's our review, starting with the things he had .
Chelsea were high energy from the off - and so was Pochettino. The Blues took the lead after just three minutes through Gallagher and it wasn't until after the goal went in that Chelsea's boss finally took his seat. Pochettino's team have struggled to maintain intensity during games, but the early goal lifted them and for once, they took advantage of it by scoring another. Shame about the subsequent collapse, but isn't that just Chelsea? It took him a while to make them but Pochettino's changes in the second half really worked. Sterling, who was used well in an impact sub role, and Carney Chuweumeka, who's looked a real gem when fit, helped Chelsea turn the tide and find a late equaliser. Noni Madueke, another second half sub, earned the penalty which tied the match. Pochettino deserves some credit for that. And now the five things he got . He might be knocking on 40, but Thiago Silva is still one of Chelsea's most reliable performers, and it was mistake leaving out this evening. The Blues looked a little shaky at the back at times and could have done with a little of Silva's composure and leadership - especially when Man Utd scored their first goal. An awful mix-up between Moises Caicedo and Benoit Badiashile gave Alejandro Garnacho an absolute gift. And it completely changed the tie. After racing into a well-deserved 2-0 lead, the game turned on a sixpence after United's first goal. And Chelsea fell to pieces. Heads dropped, players hid and soon enough it was 2-2 - and no more than the visitors had warranted. Chelsea's inability to stay composed in the face of adversity is frightening, and Pochettino has to shoulder some of the blame for that. If Pochettino's young Chelsea team are going to succeed they're going to have to learn how to game-manage. Entertainment factor aside, it was absolutely mind-boggling to see the game descend into basketball-style end-to-end chaos minutes into the second half. Chelsea were tearing United open on the counter, and then getting torn open in kind. It speaks to the team's general lack of discipline, which, as you might have noticed, Chelsea fans, keeps leading to individual errors. You can't fault Pochettino for the mistakes of his players but you can fault him for failing to keep them organised. It initially looked like an inspired decision when the Blues raced into an early lead, particularly as Cole Palmer and Mykhailo Mudryk were looking so bright. But as the game turned away from Chelsea, they could've really done with an unflappable man up top. Raheem Sterling has been poor in the past few weeks (and months), but he's a resilient so-and-so, and Pochettino could've used some of that confidence from the get-go. After going ahead, Chelsea completely took their foot off the gas and allowed United back into the tie, almost as if with a hug and warm mug of hot chocolate. They failed to take advantage of their opponent's lack of confidence. The problem is, don't have an awful lot of that either - and it was painfully obvious. In truth, when the Blues netted their second goal it was against the run of play.
