Manager David Moyes knows he will need all his tope talent to keep Bayer Leverksuen at bay.
He stated: Lucas Paquet is hugely important to us.
He's been an important part of the side, he's a well-established Brazilian international and he can bring attributes to the games which are really important to us.
You pull your hair out at times, but overall he's a pleasure to have and a pleasure to work with.
He's got some individual ability which you don't see often, but when you do you recognise it greatly and I think most people recognise that he's got some great talent.
We have to get him at his best, because at his best it gives us a greater chance."
On Kudus, he added: Mohammed Kudus is not just important for this tie tomorrow, but he's been important for us all season.
He will be important for us going forward in the future as well. He's a young boy who has only just come into the Premier League and he's settled in incredibly well.
It's not easy to start well in the Premier League, and a lot of the players who come from overseas find it quite difficult, but I think Mo, though, because of the experience he's had - in Denmark, the Netherlands and now the Premier League - it has given him a better coverage of different leagues.
We're really enjoying the way he is playing for West Ham, I think he has a lot of development to come in the future and he's settling in nicely here."
