Brighton manager Roberto De Zerbi admits his team have a few problems this season.
Despite sitting in a high position in the Premier League, Brighton have been on the end of a few bad results as well.
After struggling in the Europa League, they were thumped 6-1 by Aston Villa in the Premier League.
"We are conceding lots but listen, we have to speak honestly," he said in his post-match press conference. "We lost [Chelsea star Moises] Caicedo, we lost very important characteristics.
"We are playing in a different way because only Baleba can play with the same characteristics as Caicedo. Baleba is not ready yet. We are not ready to compete and to play every three days.
"The physical energy is not enough, in football you have to be ready to give your all and your best in the head in the mentality. We can't lose every tackle, every duel and every second ball otherwise you lose the game in this way.
"But I believe in my players because I have big confidence in the people inside of my dressing room, we are suffering a lot for this defeat but this can happen sometimes if you are not ready and you have to adapt quickly.
"We have to learn. We are suffering, it's a very bad day but maybe one of the most important days – we want to reach this level."
