"It will be a different game this time around because our defense has become even stronger. And Barcelona is perhaps not as strong as in 2015, even if they are still a great team.
"We have maybe lost a bit of physical strength in midfield compared to 2015 with the departure of Arturo Vidal and Paul Pogba, but we have more quality. And we have matured a lot since then.
"For Barcelona, Neymar has really made a step up, Javier Mascherano has gotten two years older indefence and Ivan Rakitic has matured in midfield.
"We both have a great defence, but I think ours is better, even if we both play differently."
