Napoli head coach Rafael Benitez believes Atletico Madrid's title challenge is good for La Liga.
Atleti is currently six points clear of local rivals Real Madrid at the summit of the Spanish top flight with four matches left to play.
Diego Simeone's men are also tied at 0-0 heading into the second leg of their Champions League semifinal clash with Chelsea.
Benitez, who led Valencia to a league and UEFA Cup double in 2003-04, has drawn comparisons between his own experiences a decade ago and Atleti's current situation.
"People are talking about Valencia winning 10 years ago, the double," he told Perform. "After 10 years to see another team like Atletico Madrid with a great possibility to win the title, I think it's good for the competition.
"Obviously Barcelona and Real Madrid are very strong, but Atletico are doing really well. They have the right mentality, they have the energy to achieve something important this year."
Atleti heads to Stamford Bridge on Wednesday after facing Benitez's former club Valencia in the league on Sunday.
