Atlanta United knows that if he does not win against Inter Miami, the chances of entering the playoff will be very few and that is why he asked Marcelino Moreno to please have the best game of his career to guide Atlanta united towards the victory. Marcelino Moreno has the difficult task of replacing the injured Barco.
From Atlanta United they know that if they manage to qualify for the playoffs then they could be one of the candidates to stay with the MLS Cup since they will recover another designated player by then. Ezequiel Barco could make a great pair with the new player Marcelino Moreno, so from Atlanta United they asked Moreno to be at the level of Barco until he returns.
Inter Miami's defense is not one of the best in MLS and Coach Gallagher knows it. For the same reason, he said that Marcelino Moreno will be very important for the game against Miami. The most important thing for the coach is that Marcelino Moreno can win the 1 against 1 the defenders of Inter and thus be able to break with the defense.
Atlanta United knows that this game is very important since it is in 10th place in the MLS position table but winning it could be eighth. If they lose and the teams that are below Atlanta United win, Atlanta United could be in the last places of the table and thus jeopardize their presence in the playoffs.
