Ayden Heaven was not the only former Arsenal academy member on the Manchester United bench against Leicester City.

Hubert Graczyk was a lower-key summer recruit from Arsenal after Chido Obi-Martin. The 21-year-old goalkeeper joined United after he was released by the Gunners.

Graczyk is effectively the seventh-choice 'keeper at United but was elevated to second-in-line after a spate of injuries to his fellow custodians.

Altay Bayindir, seemingly set to start in the fourth round after his third round heroics at Arsenal, suffered a minor injury and veteran 'keeper Tom Heaton also sustained a knock that ruled him out.

Dermot Mee, the reserve goalkeeper who has trained several times with the United first team, has been injured since late December and was also unavailable. Elyh Harrison, on the bench with Bayindir for the defeat to Crystal Palace, was cup-tied, having played for Chester FC in the competition while on loan earlier this season. Radek Vitek is on loan at FC Blau-Weiß Linz.

That meant the Poland-born Graczyk was included in the matchday squad for the first time. Graczyk participated in the warm-ups against Arsenal, Southampton and Brighton last month in the absence of the injured Heaton and Mee.

Graczyk's only career appearances have been four games on loan at National League South side Slough Town last season.

United have used three goalkeepers in their matchday preparations since the 2016-17 season and academy goalkeeper Will Murdock assisted goalkeeping coaches Jorge Vital and Craig Mawson before kick-off against Leicester.

Murdock, 17, is set to keep goal for United in their FA Youth Cup tie against Chelsea at Leigh Sports Village on Wednesday.

United head coach Ruben Amorim is expected to provide an update on the fitness of Bayindir and Heaton later this week.

First-choice 'keeper Andre Onana has only ever missed one United match - away to Newport County in the FA Cup last season - and that was through his commitments at the Africa Cup of Nations.
