Donny van de Beek's time at Manchester United seemingly goes from bad to worse with each passing matchweek, the £40m-valued Dutchman failing to establish himself as a regular in Ole Gunnar Solskjaer's plans despite being well over a year into his time at the club. The former Ajax midfielder was rewarded with a rare start for the visit of West Ham, but failed to impress yet again as United crashed out to David Moyes' side - the first time the Scotsman has registered a win over his former side since he was sacked from his post as United boss in 2014. Manuel Lanzini's ninth minute effort was enough to dump United out at the first hurdle, but Van de Beek was singled out by Sky Sports pundit and former England international Casey Stoney during the defeat.

"It was more than I expected, I thought we would come here cagey, test the water. While West Ham have been on top they capitalised, Lanzini holds his run, Van de Beek had no idea he was there." West Ham have been rewarded for their efforts with a clash against United's fierce local rivals and 'noisy neighbours' Manchester City in the fourth round. The result continues the theme of United's struggle this season in cup competitions, while they remain unbeaten in the Premier League, their two defeats have come in the Champions League and Carabao Cup.
