Antoine Griezmann has warned Europe's top clubs that Atletico Madrid are gearing up to win the Champions League this season.
The Rojiblancos are playing catch-up behind Barcelona and Real Madrid in the race to top La Liga but they made it three wins on the bounce courtesy of a 2-0 triumph over Real Sociedad on Tuesday.
Mikel Gonzalez's own goal put Diego Simeone's men ahead after just over 60 seconds of play at the Vicente Calderon before Griezmann doubled the lead 10 minutes in against the club he left for a reported €30 million last summer.
The France international says that Atleti have now got their confidence back ahead of next week's Champions League quarter-final, first-leg clash with Real.
"Atletico are doing well again," the France international told reporters after the win, which left them two points shy of their city rivals in La Liga. "Now we have consistency we need to keep this form going.
"We're feeling strong, we know that with our third consecutive clean sheet we are giving ourselves more of a chance of winning.
"It is normal in a season to have ups and downs. Hopefully our dip has passed and we can go on to fight to win the Champions League."
Griezmann refrained from celebrating his goal out of respect for his former employers, explaining that he would have seen such behaviour as in poor taste.
"Never will I celebrate against Real Sociedad," he added. "They gave me so much and the only reason I am standing here at Atletico is because of the work they did with me."
Atletico are still six points off Liga leaders Barcelona who - like Carlo Ancelotti's fellow title-chasers - play their game in hand on Wednesday.
After travelling to Malaga on Saturday, Simeone's men host Real next Tuesday in what is a repeat of last season's Champions League final.
