Barcelona defender Gerard Pique has hailed the selflessness of Lionel Messi, Luis Suarez and Neymar and believes the trio's lack of ego is key to their success.

According to Pique, the selflessness of Barca’s attacking trident makes them the best in the world and he praised the way they have shared the limelight since being united at Camp Nou.

The attacking trident netted a stunning 122 goals in all competitions in 2014-15 as Barcelona won La Liga, the Copa del Rey and the Champions League.

Suarez and Neymar have helped guide Luis Enrique's side to the top of the league once again in the absence of the injured Messi, and Pique believes their attitude is "magnificent".

"The key of these three is the relationship that they have," Pique told the Telegraph.

"You can see that on the pitch. It's magnificent. For example, when one is scoring a lot and the other is not scoring - Neymar, the other day, he gave the penalty to Suarez.

"When you see this kind of attitude, it means a lot.

"The only problem when you have players of this magnitude is the ego. Suarez was the main star in Liverpool, Leo before we had Suarez and Neymar; it was just him.

"And how they connect – they do not have any ego and this is the most important part.

"And they are different. Neymar is the best one-on-one. He is unstoppable. You have Leo Messi who is the most complete player in the world – he can attack, defend, he can head the ball even though he is small.

"And then you have Suarez and his first touch in the box is fantastic.

"It's really easy to win titles when you have team-mates like Messi. Well, not really easy but easier than if you have another kind of player. To have Messi, Neymar and Suarez up front, it is the best in the world."
