AZ Alkmaar coach Pascal Jansen says they'll be ready for a "battle" against West Ham United.
The first-leg of the Europa Conference League semifinal will be held tonight at London stadium.
Jansen said: "I have a clear idea of what our opponents are capable of.
"West Ham deserved to beat Manchester United in the last round of the league. Reaching the final would mean a lot to us. Of course, reaching the semi-finals is something that doesn't happen often and we are proud to be here.
"It will be a great battle, we want to see how far our possibilities can take us."
