Former Manchester United defender Wes Brown believes Axel Tuanzebe can force his way into manager Ole Gunnar Solskjaer's first team plans.
Tuanzebe has made just one Premier League appearance this season, coming off the bench to replace Luke Shaw at left-back against Everton, with the majority off his experience coming in the Champions League.
Speaking exclusively to Ladbrokes at its launch of the 5-A-Side Bet on Man United v Man City, Brown said: "Man United are so strong in midfield and up-top, but maybe they could strengthen defensively. I've always liked competition.
"I've said it many times, but when we were winning trebles and doubles, the squad was so good that you might not play well one game, but you knew you had to play well the next game because otherwise the manager would take you out.
"That comes down to the strength in depth we had in every area, and that's what the very best teams have.
"There's depth in the United squad, but players like Axel Tuanzebe haven't played enough games. I'd like to see him getting a bit more game time. But at the same time, if Harry Maguire and Victor Lindelof are fit, then the two of them will play.
"For the others, it starts off in training. That's where you need to impress first and foremost, then when you get your opportunity you've got to play well.
"The left-back situation is a good problem to have. At the moment it's Alex Telles who seems to be getting the nod but you've got Luke Shaw and Brandon Williams behind him.
"Healthy competition is always a good thing in a squad. You have to prove to the manager that you're the right guy to put in the team. Ideally you want that conundrum for every position on the pitch."
