Mikel Arteta described Arsenal's FA Cup third-round defeat to Manchester United on Sunday as a one-in-a-thousand occurrence after losing in a dramatic penalty shootout at Emirates Stadium. Bruno Fernandes put the visitors in front on 52 minutes before Diogo Dalot was sent off nine minutes later for a late tackle on Mikel Merino.

Mikel Arteta has been told he must replace Gunners striker Kai Havertz after Arsenal were knocked out of the FA Cup by Manchester United. Arsenal are the most successful team in FA Cup history but will not be adding to their 14 trophies after losing on penalties to United at the Emirates Stadium.

Arsenal boss Mikel Arteta said he was astounded his side could not finish off 10-man Manchester United in their FA Cup third round clash on Sunday, after they were dumped out on penalties having drawn 1-1 after extra time.
