Kaka admits that Ronaldinho's arrival at AC Milan has left the club with a tactical headache.
The Brazilian superstar joined the Rossoneri from Barcelona over the summer and has helped the club climb to third spot in the Serie A table.
However, a four-game winless run has threatened to derail their title tilt and allow city rivals Inter to open up a commanding lead at the top.
The disappointing run of form has come about due to a number of less then impressive showings from the club's most potent attacking weapons.
Kaka admits that being asked to fill an unfamiliar role has hindered his cause, with Carlo Ancelotti's desire to fit Ronaldinho into his starting XI proving detrimental in other areas of the field.
"Ronnie has settled in very well and he's giving us a big hand, but before we were used to playing with automatic moves consolidated over the years," Kaka told Gazzetta dello Sport.
"Me and Clarence (Seedorf) behind a forward, usually (Filippo) Inzaghi. With Ronaldinho the team has had to change set-up and we have to get used to having the same automatic moves with him.
"We play together in the national team, but it's not the same. It's a question of understanding, which is lacking a little."
Kaka admits that he is forced to 'sacrifice himself' at times for the good of the team.
"I'm trying to adapt tactically because I often find myself playing closer to the midfielders," he explained.
"I'd like to play nearer the strikers, but I understand the needs of the team. The fact is that people expect something different from me, assists and goals, and if they don't arrive I get criticised."
The former World Player of the Year has been strongly linked with a move away from Milan in recent weeks, with England touted as a possible destination.
Kaka insists he has no desire to leave Italy at present, but accepts that a new challenge in the Premier League may appeal to him in the future.
"I'm happy in Milan," he added.
"Should one day I leave it will be because my aims do not coincide with those of the club.
"But, for now that is not the case. Anyway, if that become the case, England is definitely an option."
