Roberto De Zerbi is ready to unleash Kaoru Mitoma from kick-off against Marseille.

But he says picking his XI is the toughest part of the job as he attacks on two fronts with an injury-affected squad.

Attention returns to the Europa League as the Seagulls chase the win they need to secure top spot in Group B.

Mitoma was kept under wraps until half-time against Burnley on Saturday but he changed the game when he went on.

Similarly, his second-half performance at Marseille made a big impact on the home side and their fans as he helped secure a 2-2 draw.

Albion boss De Zerbi said: “Kaoru is good. He is in good condition but we have to analyse step by step, game by game.

“At the moment he is good to play, to start the game.

“And then we have to see at half-time.

“Mitoma but also, for example, Adam Lallana, we have to manage him in the best way if we want to play with him every week.

“There are other players in the same situation – James Milner, Facundo Buonanotte.

“Lewis Dunk didn’t finish the game on Saturday but now the toughest part of work is to decide the first XI and to not take risks.”
