Lecce will face AC Milan on Sunday.
“We will have to play with intensity and care, against a side who I consider to be the favorites for the Scudetto,” Beretta said.
“They did not start well in the league, but they worked with great intensity, like they are known to do, and they got back on track.”
He added: “Our objective? It can only be to stay in Serie A: we know it will be difficult, but we have to realise we can achieve the objective even in the last minute of the last match.”
