Lucas Moura looks set to lead the line for injury-hit Tottenham's Champions League round of 16 first leg against RB Leipzig in the absence of Son Heung-min.
Son faces a spell on the sidelines after suffering a fractured arm in Spurs' Premier League win over Aston Villa on Sunday.
With Harry Kane still absent due to a hamstring injury, Tottenham are without a recognised striker in the starting line-up to face Leipzig on Wednesday.
It appears Alli could move into a more advanced role, with Lucas up top and Steven Bergwijn also offering support along with Giovani Lo Celso.

Timo Werner will provide Leipzig's main attacking threat in a contest that will see Julian Nagelsmann become the youngest manager to take charge of a Champions League knockout match at the age of 32.
