#2 Lucas Moura
Mauricio Pochettino may very well decide that he cannot alter the team's playing style to fit Fernando Llorente's main strengths. So with that in mind, the next viable option would be to use Lucas Moura in a false nine role.
The Brazilian international would be more suited to that role than Dele Alli, Christian Eriksen and Eric Lamela - with eight goals and an assist created in 20 starts across the Premier League and Champions League this season. He possesses pace, dribbling ability and high technical quality too. His hold-up play and passing are also very good, which makes him better suited to the role than Spurs' other attackers.
The former PSG forward would also provide the element of surprise to the Tottenham frontline. This could be very vital - as coaches and defenders may not know how to defend against him as a frontman. However, Lucas is just returning from injury after sustaining a knock during their 9-0 cup win over Tranmere.
