Juventus midfielder Arturo Vidal is reportedly a doubt for his side's Champions League quarter-final tie with Monaco this week.
The Chilean is a key player for the Bianconeri and he scored the only goal in last week's first leg victory over the Ligue 1 club.
According to SportMediaset, Vidal has been suffering from acute tonsillitis and will be evaluated by the Juventus medical staff on Tuesday.
He was forced to miss the club's 4-0 win over Hellas Verona in January after being hospitalised with tonsillitis.
Vidal has scored seven goals in all competitions for Juventus this season.
