The Toffees only managed a 2-2 draw at home.
Yakubu told Channel Five: “We’re a little bit down but we have to think about the next game.
“I think it’s going to be difficult but we have to work hard in training – we’ve done it before. And we have to believe in ourselves that we can do it.
“They’re a good team and we worked so hard so we’re just lucky. We had some chances and we just didn’t take them.
“It’s difficult when you go behind because you have to work hard but for me, it’s better that we didn’t lose the game, though we didn’t get the result we were looking for.”
