SEVILLE • Sevilla's wild-eyed, excitable Jorge Sampaoli faces Juventus' phlegmatic Massimiliano Allegri in a fascinating clash of coaching styles in the Champions League today.

Both sides are unbeaten in Group H and seem set to qualify though Sevilla, on 10 points from four games, need a draw and visitors Juve, on eight, a win to guarantee a last-16 place.

Sampaoli has already brought a breath of fresh air to the Spanish Primera Liga, where his side have climbed into third place and beaten Atletico Madrid along the way.

The shaven-headed Argentinian made history last year when he led Chile to their first Copa America title, on home ground.

The 56-year-old likes his team to play with a fast and furious style, sweeping forward in relentless waves with seven or eight players joining the attack.

Allegri, 49, also likes his team to dominate possession but he is averse to risk-taking and often talks of the importance of "administering the match".

Unlike Sampaoli, he is established in European football having won a Serie A title with AC Milan and two at Juventus, who he led to the Champions League final two seasons ago.
