Edinson Cavani has backed Luis Suarez to succeed after a period of adjustment at Barcelona, though he says he needs more time to form an effective partnership with his countryman for Uruguay.
Suarez has scored eight goals in 24 appearances in all competitions for Barcelona this campaign after returning from a four-month ban, a sharp downturn after his 31 goals for Liverpool in the Premier League last season.
But PSG's Cavani told Marca Plus that his striker partner with the Uruguay national team is still adjusting to life at the Camp Nou.
"Luis is getting used to playing a different style of football than he did at Liverpool," Cavani said. "Surely it won't be easy for him. It is a difficult playing scheme because there is a lot of movement and Barca is not used to playing with a 'pure 9.'
"With Luis Suarez's fitness and talent, I am sure he gives a lot to Barca.
Barcelona have a wealth of options in attack, with Lionel Messi and Neymar leading the way, and Cavani said Suarez must find new ways to contribute.
"I think that if a team are used to playing a certain way one has to find a way to adapt to their system," Cavani said.
"But it depends, because a coach must look for a style of play that adapts to a certain forward because many times I think when you play with a fixed attacker you have to work out a system by which all plays finish with him. But it depends on the coach's preference."
A knee injury sidelined Suarez for Uruguay's opening match of the World Cup against Costa Rica, and Cavani scored in a 3-1 defeat. They played together in the next two games, with Suarez scoring twice against England before famously being sent off for biting Italy defender Giorgio Chiellini.
Thanks to Suarez's resulting ban, the strike partners have only played one match together since then, a friendly against Uruguay in November in which they both scored.
Cavani said their partnership is still a work in progress.
"Well, we are both attacking forwards so it is sometimes difficult to understand and to outline our preparation," Cavani said.
"We have had little time to do that on the national team, but I know that with a little bit of work we can understand each other better."
