Lionel Messi insists Barcelona must improve their all-round performance if they are to stand a chance of winning the Champions League this season. The Blaugranas were set to host Serie A club Napoli for their Champions League last-16 second-leg clash, but the COVID-19 crisis brought football to a halt. Los Cules played out a 1-1 draw away at the San Paolo stadium in February, and the six-time Ballon d'Or winner Messi says if they are to overturn the result against Napoli and also win Europe's elite competition, Quique Setien's side must change their approach in the upcoming matches. "I never doubted the squad we have and I have no doubt that we can win all that remains, but not by playing in the way we were playing," Messi told Sport.

Mine is based on the fact that I was lucky to play the Champions League every year and I know that it is not possible to win it by playing as we have been playing. Perhaps Setien misunderstood." The Argentina forward, who has won four Champions League titles with Barca, continued: "This break may end up benefiting us, but we are going to see if they can start the competitions and there we will leave doubts because we will check the level that we have or can reach when we start. "Going back to training is a first step but we should not trust ourselves and we must continue taking all the necessary precautions and assume that we have to start playing the games when they arrive but behind closed doors.

"Personally I am looking forward to the competitions. We know that everything is going to be weird, without fans in the stadium, and with the theme of the concentrations that we really would not like to have to be separated from our families. You have to see how it looks." Messi added: "Physically I feel very well. I was training at home these days and I think it helped me to keep fit. "Very hard confinement, but with the children and with Antonela everything ends up becoming moments that I try to enjoy all together."

Spanish clubs returned to individual training this week after the coronavirus chaos brought football to a standstill since March.
