Lamouchi knows that they face a challenge to progress in the competition but wants his side the come away from the game with their heads held high, regardless of the outcome.
He said: “It will be very tough. They are one of the best teams in the Premier League, they have a young manager with quality players. They are a fantastic team, it is a nice stadium and we want to make sure that it is not ridiculous, to disturb them and give a good image of our club and our team.
“We can’t compete at the same level as them but it is one game away from home. We must try, we must play, we must enjoy, fight, run all together because it will be a very tough game.
“I would be happy with a draw, but our goal is not to win the FA Cup. We want to go there, disturb them and try to play our game with a good performance.
“We have nothing to lose, we just want to try and enjoy it.”
Lamouchi said he will make changes to the side as he rotates his squad following the busy festive period, with opportunities available for squad members to impress.
“I will prepare my team, my players, in the best way with the best line-up,” he said.
“We want to give some game time to some players, we will make some changes but not too much; it is necessary for the rest of the season, especially now.
“We have played a lot of games in a few days, so we need to give opportunities to players to play. I also want to compete with the opponent, so to change completely is not possible.
“Maybe we will see some younger players, to play maybe but to come with us, probably.”
