Roberto De Zerbi has explained why the 1-0 win over Marseille was so special.

Joao Pedro’s late goal takes Albion into the Europa League last 16 as Group B winners.

De Zerbi was emotional at full-time as his side grabbed the points against Gennaro Gattuso’s well-organised OM.

He then spoke about a Serie C play-off defeat he suffered as Foggia boss when he went up against Gattuso’s Oisa.

De Zerbi said: “This game in a way closes a circle.

“It was against Rino Gattuso I lost the most important game of my career up to now.

“This win I dedicate to my former players at Foggia, who lost the match, and to the fans.

“This defeat will always stay with me but it’s like today – everyone won together.”
