Joao Felix's finishing:
The Portugal international is a joy to watch at times. He's got a wonderful ability to get out of the tightest of situations with the ball still glued to his feet. But, for all his attributes, and he does have plenty, finishing is not one of them. Remember, he scored just 34 goals in 131 games for Atletico Madrid, while he's only netted four times for his country. He was never likely, then, to suddenly run riot at Chelsea. However, one is perfectly entitled to expect a player of his undoubted quality to convert the second chance he had in Dortmund. The goal was at his mercy and yet he somehow construed to crash the ball off the bar. It cost Chelsea the game, and could yet end up costing them the tie too...
Mykhailo Mudryk's first touch:
The Ukrainian's potential is obvious, his pace absolutely breath-taking, but he's far from the finished article, which is quite something given his transfer fee. There is a worrying lack of control right now; at times, it's almost as if he is too quick for his good, as underlined by the way in which he never quite got the ball out of his feet after being released into acres of space by Felix early on. The net result was that he ended up being dispossessed on the edge of the area. Then, just moments before he was subbed midway through the second half, his pace got him in behind the Dortmund backline once more but he failed dismally to control a lofted pass from Kalidou Koulibaly. Mudryk scares defenders. He should develop into a serious and constant threat but it's clear that it will take some time and patience to polish this roughest of diamonds.
Had the Blues boss got the victory that his team arguably did enough to earn (their xG was 2.13, to Dortmund's 1.41), he would have become the first English coach to win five consecutive games in the Champions League, which would have gone some way towards easing the intense pressure he is under. As it was, though, Europe provided no respite for the former Brighton manager. Indeed, Chelsea have won just two of their past 12 games in all competitions, and tasted victory just once in 2023. This is obviously a team in transition, one in the middle of the most expensive overhaul in football history. It can't be easy working in such an unstable environment but there's no denying that Potter's results simply aren't good enough right now. He needs to mastermind a second-leg turnaround to buy himself more time to work with this expensively-assembled side.
