Chile manager Jorge Sampaoli has revealed that Louis van Gaal is uncertain over the fitness of top target Arturo Vidal after the player recently had knee surgery, therefore putting his potential switch on hold, Daily Mail reports. 

If the Manchester United manager believes the midfielder isn’t ready to step into the role, he could end all negotiations and look elsewhere for his key central figure.

With a huge price tag of £47 million, Van Gaal isn’t willing to take the risk that could see the likes of Vidal continue to suffer injuries on the knee which has already troubled him in the past. 

“I know that the main problem in Vidal’s $80m (£47m) transfer from Juventus to Manchester United is Louis van Gaal’s doubt over the improvement of Arturo’s knee,” Sampaoli told the Chilean media. 

Despite the fact he was fit to play in the World Cup, the Argentine coach believed that his star player was nowhere near 100% and his form couldn’t be compared to that of when he played for Juventus.
