Juve defender Stephan Lichtsteiner has undergone surgery and is expected to return in 30 days.

The Swiss international left the pitch complaining of breathing difficulties in Juve’s 1-1 draw againt Frosinone and hasn’t featured since.

“During last week’s match with Frosinone, Stephan Lichtsteiner suffered breathing difficulties due to a benign cardiac arrhythmia (atrial flutter) which later stopped of its own accord,” a statement on the club’s official website announced.

“Tests and specialist consultancy conducted over the following days suggested surgery to be the best course of action for the defender.

“Dr. Gaita today performed a cardiac ablation operation and Lichtsteiner is expected to return to competitive action within 30 days.”
