Barcelona striker Luis Suarez has urged the club "to not use common sense" in their efforts to agree a new deal with teammate Lionel Messi.

The Argentina international is locked in negotiations with the La Liga giants about an extension to his current contract, which is due to expire in 2018, with wages thought to be the sticking point.

Barca chief executive Oscar Grau yesterday insisted that the club needs to have a "cool head and common sense" in the negotiations and not commit to salaries beyond its expected budget.

Responding to the comments, however, Suarez pleaded with Grau to put aside his stance and do whatever it takes to tie down the hitman for the long term.

"Messi is the best player in the world," he told Marca. "What has to be done is that the club needs to renew his contract and to not use common sense."

Suarez penned fresh terms last month keeping him at the side until 2022.
