The Argentina international scored the opening goal in Liverpool's 3-1 victory over Crystal Palace, helping the Reds return to fourth place in the Premier League.
It was his fifth goal of the season across all competitions and his first in the league, with Mac Allister explaining that the team's tactical approach has encouraged him to make more frequent runs into the penalty area.
“I like scoring goals, being in the penalty area and fortunately the coaching staff understand that. They want me to attack that space,” he told AS.
Mac Allister's future at Anfield was also discussed, with his current contract running until 2028. The midfielder made clear that his commitment to Liverpool remains unchanged, although his comments suggested he is hoping his performances will eventually lead to a positive development regarding his future.
“I have always given my maximum. I will give 100 per cent and, hopefully, maybe they will change their minds.”
The midfielder also reflected on Argentina's future as the national team prepares to face the prospect of competing without Messi.
The former Barcelona and Paris Saint-Germain forward has been central to Argentina's success for many years, making the transition to a new generation particularly significant for the reigning world champions.
Mac Allister admitted that the prospect of playing without his former captain would take some getting used to, but insisted the responsibility must now be shared across the squad.
“It will be strange. We still cannot get our heads around the fact that Leo will no longer be with us.
“Leo is something unique and there will never be anyone like him. We have to become stronger as a collective because we no longer have that player who can completely change a match.”
Rather than looking for one individual to reproduce Messi's influence, Mac Allister believes Argentina must develop collectively and ensure the next generation is supported as it establishes itself internationally.
One player he believes could become particularly important is Nico Paz, the attacking midfielder who has impressed at Como after previously developing within Real Madrid's system.
Mac Allister was full of praise for the youngster's technical ability and believes the responsibility of helping him fulfil his potential belongs to the entire national team.
“He is a player with incredible quality and talent. The most important thing is that we, as a group, can help him reach the level he is showing at Como.”
For Mac Allister, Argentina's next chapter will involve a significant adjustment, but he believes the squad has the collective responsibility and quality to move forward.
At Liverpool, meanwhile, his immediate focus remains on maintaining his contribution, with his attacking instincts increasingly becoming an important part of his game.
