Bilic faces a dilemma after many players shone in the 3-0 victory over lowly Bolton in the EFL Cup.
The Hammers boss made 10 changes to his side from the goalless draw with West Brom in the Premier League last time out and now claims he is unsure of who to select against Spurs.
Bilic said: “I said to the players before the game, 'every one of you who thinks he deserves to be playing ahead of the guy who is playing, impress me and my staff – give us a headache with your performance'.
“We are more positive after this performance from some of the players, we have more to choose from. It’s very good and we’re going to need it on Saturday, definitely."
