Speaking to the Manchester Evening News , he said : `` I do a lot of work in the gym , ' Januzaj said . ' I am trying to be faster and stronger so I can be tougher when I go out on the pitch . ' I am doing a lot of short , sharp stuff so , when I turn a defender or go past a player , I can just get a few metres away from them with my acceleration . ' Louis van Gaal ( right ) has given the 20-year-old only eight starts during an inconsistent season . Januzaj shares a joke with team-mates ( L-R ) Andreas Pereira , Juan Mata and Ander Herrera at training .
