Atletico Madrid are set to enter the race to sign Alexandre Lacazette from Arsenal.
Luis Suarez fired Diego Simeone's side to a first LaLiga title in seven years last season but the Argentine coach wants to bring more competition to his attack as his side relied heavily on the Uruguayan for goals.
Suarez scored 21 goals for the Rojiblancos, including winning strikes in their final two wins of the season against Osasuna and Real Valladolid as they pipped neighbours Real to the title by two points on the final day.
