A goal and an assist. Not the worst night for Antonio Rudiger. Unfortunately…
The goal was Arsenal's first-half equaliser; the assist, their second-half winner. Not that Rudiger could have done much about either. These were hapless deflections more than horrible errors, a scruffy influence on what was often a scruffy game. Not that Arsenal were complaining.
This win takes them to Wembley again, for the first domestic cup final since their last visit in May. Manchester City will be favourites on the day, of course, but so were Chelsea over two legs here. Arsenal were decent value for their win, though, even if Chelsea will rue the chances missed by Alvaro Morata in the first game. They could have had a reasonable cushion here.
Chelsea even got a corner, the final play of the game. Ross Barkley had one job on his debut – make sure he didn't plant it into the first red shirt. He failed and Michael Oliver blew the final whistle. It was an inauspicious start for Chelsea's new signing. He hadn't played a competitive first-team game since May, and it showed.
The winner was fortunate but not undeserved overall. Alexandre Lacazette, quiet otherwise, held the ball up well on the right against Andreas Christensen, before attempting a cross which clipped the legs of Rudiger. Having already diverted the ball into his own net with his head, he could have done with a break. He didn't get it.
The rebound took the ball directly to Xhaka, who prodded it past second-string goalkeeper Willy Caballero. Ah well. A Carabao Cup final appearance is hardly going to influence the long term future of Chelsea manager Antonio Conte. These things do matter to Arsenal though. They may be losing ground in the league, but Arsene Wenger he has turned them into an excellent cup side and some would even argue those recent successes have extended his tenure.
