The defender spent a successful spell at Falmer Stadium under Potter, before joining the Blues last summer.
Marc Cucurella believes Chelsea should give Graham Potter enough time to repeat his success at Brighton.
Following an impressive start at Chelsea, Potter saw his side suffer a sudden dip in form in the month leading up to the World Cup.
Chelsea ended the first half of the season with a disappointing run of six winless games as they slipped to the eighth spot on the Premier League table.
Thomas Tuchel’s sudden sacking earlier this season indicated the impatience of Chelsea’s new hierarchy. But Cucurella believes the Blues need time to implement their new manager’s ideas.
“We have big players to do his ideas,” the Spaniard told the Sun. “I was really happy at Brighton with him and now he has come here and I think it is good for me and the rest of the team. He is a good coach because his idea of football is attacking.
“All of it is a process. The first season with Graham in Brighton the results were not good, they stayed down in the table.
“They continued with the same ideas, working, working and working. Then, last season and this season they played really good with the same ideas.
“We need to work and understand his ideas and the results will arrive.
“It is difficult because it is a new coach with different ideas and it is difficult to change without the time to train.
“This part of the season we have time, we meet more and know the ideas of the coach. This second part of the season, I am excited for.”
Chelsea will return to Premier League action when they host Bournemouth on December 27.
