Manchester United manager Louis Van Gaal is stalling on a potential bid for Juventus midfielder Arturo Vidal due to concerns over his knee troubles, according to the Chile national manager, Jorge Sampaoli.
The 27-year-old is one of Europe's hottest properties so far this summer, and his future has been dominating headlines since the end of the 2013/2014 campaign, but as of yet, no formal offers have come in for the Chilean, despite his impressive performances for Juve last year.
Vidal, who joined the Serie A giants from Bayer Leverkusen in 2011, has enjoyed a successful career in Italy, but after becoming one of the best central midfielders in the game, interest in him has been high, with three Premier League clubs all interested in signing him this Summer, as well as others around Europe.
Manchester United, Liverpool and Chelsea have all been monitoring Vidal's situation at Juve, and despite all three being interested in signing the midfielder, no official formal bids have been made, despite reports suggesting United have approached the club three times.
It was believed that The Red Devils had offered from £35million to £47.7m, but those figures have been dismissed, and reports in Italy have claimed that no formal offers have been made at all.
Reports of medical tests taking place in Chile have also been dismissed as it was reported that Vidal took several fitness tests for United, which he was believed to have passed, but according to Sampaoli, his previous injuries and fitness levels is what's stalling a potential move to United.
According to the Chile boss, Louis van Gaal is concerned about spending such a large sum of money on someone who has just suffered a serious knee injury, and Sampaoli believes that that's what is putting off United from making any formal bids.
Vidal was a huge doubt for the World Cup in Brazil due to knee cartilage surgery just months before the competition, but he managed to compete and manage to avoid any more serious damage, but Sampaoli believes Van Gaal is still anxious on his fitness levels.
"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 Chilean newspaper El Mercurio.
