3. Arturo Vidal
The Chilean midfielder was heavily linked with a move to Old Trafford during the summer with reports suggesting United were willing to pay up to £40 million for the Juventus enforcer.
However, as the transfer window neared its end, van Gaal and his staff seemed to get cold feet and ended their interest in Vidal. This could have been mainly been down to the 27-year-old’s recent problems with injury.
If the Chile international can prove his injury problems are behind him, Van Gaal may reignite his interest in January.
