Juventus coach Max Allegri admits it's always a test facing Maurizio Sarri.

Juve meet Sarri's Lazio on Sunday.

Allegri said, “I expect a difficult match because Lazio are a strong side who are doing very well. It will be a different type of game to the one with Verona. Having said that, if there's a goal after 10 minutes then everything could change.

“Sarri is a great coach who knows how to organise his teams defensively and has a lot of quality players who can create situations both with passing moves and on the counter.

"We both won the Serie A title at Juve, but in terms of personality, Sarri and I are polar opposites."
