Fonte has wasted no time settling into his new surroundings following his £8million move from Southampton and has already got to know his new team-mates following a full week of training.
The 33-year-old is expected to go straight into the squad for the big game against Pep Guardiola's side and says he is looking forward to coming up against Sergio Aguero and the other City forwards.
Fonte said: “They have great strikers and one of the best forwards in the world in Sergio Aguero but if we produce a good display it will be an easier day for me.
“I relish this kind of challenge. I have played against City a few times but it is about the team and not the individual. I hope we can get a good result.”
Fonte looks set to play his first game alongside Michail Antonio and already has a special relationship with the Hammers forward, having played alongside him at Southampton.
The duo enjoyed a memorable spell together on the south coast after helping the Saints to win the Johnstone's Paint Trophy at Wembley back in 2010.
Fonte is now hoping they can enjoy even more success together playing for the Hammers and has nothing but praise for the way Antonio has established himself as one of the top performers in the Premier League this season.
Fonte added: “Michail was only young at the time. I was young at the time as well! He had raw pace, talent, explosiveness and we could see the potential in him.
“He was fantastic in the Final and scored a goal. It was a great day at Wembley.”
“He has been outstanding and has done really well for himself. I am happy for him and I just hope he can continue to help the team so we can have many more wins.”
