Juventus goalkeeper Wojciech Szczesny will miss the start of the Serie A campaign with a left thigh injury suffered in a pre-season match against Atletico Madrid, the club said on Monday.
Polish international Szczesny, who played 40 matches in all competitions for Juve last season, felt discomfort near the end of the first half in the 4-0 defeat by the Spaniards on Sunday.
"He underwent radiological exams this morning ... which revealed a low-grade lesion of the adductor longus muscle of the left thigh," Juventus said, adding he could be out for 20 days.
Juve finished fourth last season in their second successive campaign outside the top three. They open their Serie A campaign against visiting Sassuolo next Monday before games at Sampdoria (Aug 22) and at home to AS Roma (Aug 27).
