Pochettino says Romeo Lavia is always a chance for the game.
He said, "We need to assess tomorrow and then decide. They are close, but we need tomorrow to take the decision."
"Maybe Lavia is the more difficult [one]. But we need to assess Nkunku."
On Brighton, he added: "They are doing a fantastic job and of course they are a very good team with very good coaching staff. I know very well Roberto [De Zerbi] and I think he is doing a fantastic job."
