Former Arsenal goalkeeper Graczyk officially joins Manchester United

The 21-year-old goalkeeper quietly made his move to the club earlier this transfer window, flying under the radar.

He is linking up with their Professional Development Squad and will slowly transition to the first team.

Taking to his Instagram page on Tuesday, Graczyk posted: "Buzzing to have signed for this massive club, let's get to work."

The Red Devils snared Graczyk after he was released by Arsenal in the summer.

The Gunners may not have felt that he is good enough to become a Premier League shot stopper.
