We go head to head with the Hammers in the fourth round of the competition just a month after a 3-2 win at the London Stadium in the Premier League.
Mauricio is determined to continue the team’s momentum of seven straight wins in all competitions. "It’s a London derby against West Ham, always important,” he said.
“It’s true we come from a very busy period and we have a very busy period ahead with great games and it’s important to provide the team with freshness.
“We know it will be tough but it’s important to trust the squad and trust everyone to show they can play and help the team keep that momentum.
