Chris Basham believes the return to fitness of David Brooks will boost United's play-off push in the coming weeks.
The Welsh international played 45 minutes on his first-team return at Leicester City on Friday evening following a bout of glandular fever and Basham acknowledged the Brooks has been missed.
Speaking of the 20-year-old and his emergence this season, Basham remarked: "During the Adkins regime, Brooksy was there or thereabouts and I always thought he would breakthrough into the team.
"When he comes on the pitch, he cruises through games and glides past defenders, he is similar, although doesn't have the stature of his Welsh team-mates, Gareth Bale."
Basham added: "He is improving all the time, he drives at players, he's strong and he can change a game. We've missed him, he brings defenders into the game and makes them make tough decisions.
"Unfortunately the illness really took it out of him, but thankfully, having looked sleepy for the last couple of months he seems to be getting fitter and stronger everyday and he'll be a big player for us in the last 15 games."
