Diego Simeone has no regrets over selecting Diego Costa for the 2014 Champions League final - likening the Spain striker's influence over Atletico Madrid at that time to Lionel Messi's at Barcelona.

Costa helped to fire Atletico to a stunning LaLiga title win in 2013-14, scoring 36 goals in all competitions.

However, a thigh injury dogged him during the final weeks of the campaign and he lasted only nine minutes against rivals Real Madrid in Lisbon.

It would prove to be Costa's final appearance for Atleti before moving to Chelsea, and his team-mates went down to a 4-1 extra-time defeat after Sergio Ramos equalised for Madrid deep into stoppage time.

"If I had it all over again, he'd play the final from the start again. How could our best player not play?" Simeone told AS of the player he looked to bring back to the Vicente Calderon last year.

"He wasn't injured! Did you see the 100m sprints he was doing out on the pitch?

"I said: 'If this lad can give me 45 minutes in the Champions League final...' It's Diego Costa!

"It's like Messi being at 50 per cent and not playing for Barca in the Champions League final. For us, Diego Costa was our Messi."

Simeone said losing to Madrid in Europe's showpiece final in both 2014 and 2016 affected him "deeply" and feels his players' feat in recovering impressively from such setbacks will be remembered fondly for years to come.

"Any other team that lost two finals in that way - other than Real Madrid, Barcelona or Bayern Munich, clubs that are so used to playing finals - would have gone into decline," he said.

"Time will bear out the importance of what we achieved. It'll be historic, legendary."
