McTominay struck accurately from a Marcus Rashford‘s setup seven minutes into the additional 30 after West Ham United had managed to frustrate their host for the entire opening 90.
United almost found a breakthrough in the first half but Victor Lindelof’s header was kept out by a superb one-handed Lukasz Fabianski save shortly before the half-hour.
The visitors put in a much-improved performance after half-time although United still enjoyed the best chance, with Marcus Rashford denied by another point-blank Fabianski stop, before Craig Dawson almost won the tie with a glancing header from a corner late on – and in extra-time, McTominay’s finish would make all the difference.
