Asmir Begovic is confident Bournemouth can cause an upset at Vitality Stadium on Saturday.
The Cherries host title contenders Liverpool on the back of a win over Huddersfield Town on Wednesday.
Speaking before the game, the Bournemouth goalkeeper said: "They have spent a lot of money and added a lot of quality. They have strengthened really well so have kicked on again. They are right up there with Manchester City and it will be a huge challenge for us.
"We will prepare as normal and look forward to playing a world-class team with world-class players. We are at home so will try to give it a go.
"We go into every game trying to win and know it is going to be extremely difficult. We will have to be smart and put in one heck of a performance but everything is doable and we will give it our best."
