Liverpool are hoping that they can tie up a deal for Atletico Madrid striker Diego Costa after offering the Brazilian the chance to triple his salary by moving to Anfield this summer.

Reports emerged last week claiming that Liverpool had made an initial offer for the striker and now Spanish publication Marca claim that the Premier League club are willing to offer Costa around €4m per year.

Costa is one of the lowest-paid players at Atletico, despite last season forming an impressive partnership with Radamel Falcao that helped the club achieve a third place finish and qualify for this season's Champions League.

The Brazil international also scored in the Copa del Rey final as Atletico overcame bitter rivals Real Madrid, further putting him in the spotlight.

Marca report that Arsenal have also shown an interest in the striker but it is Liverpool who are working hard to complete a deal as they attempt to further bolster their squad ahead of the new season.

Liverpool have already signed one striker in Iago Aspas, but with much speculation over the future of Luis Suarez, Rodgers may well feel he needs another option in case they receive an offer for the Uruguayan which is simply too good to turn down.

Costa scored 20 goals in all competitions last season and was handed his first cap for Brazil by Luiz Felipe Scolari after much speculation that Spain were hoping to convince him to represent La Roja.

The 24 year old does now hold a Spanish passport after living in Spain for six years which would make it far easier for Liverpool to push through a deal.

It is believed that Costa's agent Jorge Mendes has been in discussions with several European clubs and Liverpool are fully aware that an offer of €25m would activate the striker's release clause.
