Barcelona midfielder Andres Iniesta has hailed the club's attacking trident of Lionel Messi, Luis Suarez and Neymar as the best strike force he has ever played with.

Iniesta has won 22 trophies in a stellar career at Barca playing alongside the likes of Ronaldinho, Thierry Henry and Samuel Eto'o, but he believes the South American trio's return of 117 goals this season puts them on another level.

"I have had the chance to play with the best strikers in the world at this club. At the moment to have these three players is something incomparable," he said.

"For me all three are the number one, all three are still young and have spectacular potential."

Iniesta has the chance to add a 23rd title and a third Copa del Rey to his honours list when Barca face Athletic Bilbao in the Copa del Rey final on Saturday at the Camp Nou.

Victory would seal the second leg of a potential treble for Luis Enrique's men with the Champions League final against Juventus to come on June 6.

The Spanish international was part of the only previous Barca side to win the treble in the 2008/09 season and sees similarities between the two sides.

"No two seasons are the same. I see similarities with the treble season because we are back to playing for everything," he added.

"The feelings among the group are very good because we wouldn't be in this situation if they weren't.

"We know we are close to something very important that almost never happens. They are two games and we want to take another step to win the two titles that are left."

Barca were further boosted as Enrique confirmed Suarez will be fit to start despite missing the final two league games of the season due to a hamstring problem.

And the Barca boss insisted that his side won't let their minds wander ahead to next weekend's meeting with the Italian champions in Berlin.

"I am preparing for one final, tomorrow's one," he said on Friday.

"There isn't another final for me right now. I know Juventus and what we have to transmit to the players we can starting from next week."

"We are desperate to win the Cup. I wouldn't put one title above another because it is an opportunity that doesn't come around often."
