Speaking ahead of the clash on Sunday, Guardiola described the game as going to be tough but expressed optimism that his side will win the match.
“One game left – it will be so tough like today – we are away and we saw Brighton had a good game at Arsenal,” Guardiola told BBC Sport.
“But it is in our hands, don’t forget but we could have been 10 points behind if we lost to Liverpool here [on January 3].
“We were seven points behind, but we are in the last game and it is in our hands. We are going to prepare well.
“We’ll see if Brighton defend deep or will be more offensive. It will be tough, but hopefully, we will have the performance to be champions.”
