It looks like Brooklyn Beckham is really taking this whole, following in your father's footsteps, thing pretty seriously!!
While it's unclear if the practice session will actually turn into anything, it's still pretty good sign as one source says:
"He was there with his dad and took part in a practice session with one of the academy sides. It was a chance for him to impress. If he’s done well then no doubt the club will look at taking him on."
Becks played for the Red Devils for a decade and won the premier league six times and scored a whopping 62 goals!
Needless to say, he's a bit of a legend at Man U, and it sounds like they might at least be a little interested in keeping the Beckham name at Old Trafford!
