Kessie says Milan's players still believe in European qualification.
“It's going to be a very complicated game, so we must do much better than we did against Juve," Kessie told Sport Mediaset. “Lecce are on home turf and really fired up.
“We are in the running for a place in Europe, it's all very tight in the table. We've got to pick up points in every match to take Milan as high as possible, playing every game as if it was a Cup Final.
“It wasn't easy for us staying locked up for all that time, so now we're really fired up and raring to get back on the field. Playing behind closed doors takes some getting used to, but we have to keep doing it until there's no risk of anyone getting sick."
