Juventus coach Max Allegri insists there's no problem with Paulo Dybala.

Dybala was caught muttering an insult towards him as the Argentine was substituted against Udinese.

Allegri said, “There is no problem. At that moment I needed a player who could attack on the counter and substitutions are part of the decisions a Coach must make.

“These strikers have always scored goals and always will, there are just moments for everyone when for three or four games they don't find the net. The important thing is to keep doing the usual performances.

“This game is worth three points, just like last weekend and the next. We must have great respect for SPAL, as they play attractive, attacking football and suffered narrow defeats, causing their opponents big problems. We must get back to winning on home turf."
