The pair performed together for the first time in the absence of Paolo Di Canio through suspension on Saturday and Jermain declares: "I definitely thought we played really well together, me and Fredi. A couple of times he played off me and I played off him.
"Considering it is the first time we have played together it was good; we had only done it in training just once or twice, and it will be interesting to see who is picked against Leeds."
Jermain was denied a goal by the brilliance of Jerzy Dudek in Liverpool's goal, and the young striker says: "He is a great keeper, one of the best in the league and some of his saves were unbelievable, especially the one in the first half; Fredi headed it down and I've turned and bent it - I really thought it was in.
"I turned round, looked, and thought 'yeah that's in', and his hand came from nowhere and tucked it round the post.
"He also made great saves from Don's header, Trevor Sinclair's overhead kick, and other chances, and overall I thought we were the better side.
"In the second half they had to go for it, they were so stretched, and it was two against two a lot of the time.
"We deserved a win because we played so well and everyone worked hard - we were all down afterwards because we played so well.
"There is a long way to go, everything is possible, but we have to keep on working hard and you never know."
Jermain is a confirmed admirer of Michael Owen, whose goal undid the Hammers, but he says he is his own man.
"I'd rather be known as myself so little kids can say 'I want to be like Jermain' in the future," he insists, "but obviously I look up to him even though he is still young himself."
Jermain is hoping for more of the same at Elland Road whether he starts or not, and he adds: "We have Leeds next on telly and hopefully we can put in the same performance and get three points. They have got Smith, Viduka, and Fowler, though Keane is injured.
"It will be tough but I am confident we can get three points and all we can do is look forward to the next game."
