'Big challenge' - Alisson aware of problem he faces with Liverpool team-mate Luis Diaz

Alisson Becker has recognised his Liverpool team-mate Luis Diaz is likely to cause him and the rest of the Brazil squad problems when the two countries go head-to-head at Copa America next week.

Brazil all but booked their place in the quarter-finals of the competition with a 4-1 win over Paraguay in the United States on Friday night, requiring only one point in their final group game, though the battle for top spot in Group D remains alive with one match to play.

Diaz helped Colombia make it two wins from two at the tournament after converting a penalty in a 3-0 victory at Costa Rica's expense, leaving his country two clear of the Selecao after a goalless draw in their Copa America opener.

Brazil and Colombia will now go head-to-head in the early hours of Wednesday morning (UK time) to determine which country will progress in first place and Alisson is all too aware of the dangers Diaz and the rest of Los Cafeteros' squad will pose.

"Theoretically (Colombia) will be the toughest opponent in the group stage, although Paraguay played a great game until they were 3-0 up, then they dropped their level due to the score, but we know that Colombia has been playing very well, they have a very strong attacking power, a solid defence and tough players," the Liverpool No.1 told Sportv after helping his nation to a valuable three points on Friday.

Alisson added: "It will be a big challenge, but we are prepared and we will prepare ourselves in the next few days, with rest, mentally, in training, to come up with the best strategy to face Colombia, play a great game, maintain this high level of performance and improve in whatever way possible.

"When we drew in the first match, we remained calm: 'calm down, everything is not wrong. In here, calm, outside everyone talks and takes part. In here, calm'. And just as we won 4-1 today, we won't either. We are very excited, let's remain calm, calm, because today we can also improve some aspects. This is the mentality here within the team, we are here very seriously, doing our best and representing our nation."

Commenting specifically on the response shown by Brazil to overcome the disappointment of their 0-0 draw with Costa Rica on Tuesday, Alisson stated: "In football, we need to have conviction. It's not just about coming here, playing a game and going home. It's a competition and, if we want to win, we have to have conviction. Dorival [the manager] has conviction, he's putting his face on the team, the way he likes to play, the way he likes to defend. It takes time, but the response from our team, from all the players, was very good.

"The last match (against Costa Rica) was just missing a goal, and today we showed that. When you score a goal, the match takes a different direction, so it's important to defend well, not to concede goals early in the match. That's what we did here, we got a 3-0 score in the first half. That gives us peace of mind for the rest of the match."
