When that situation occurred, Mourinho had very few options at his disposal to replace his two main goalscorers, and at times played Dele Alli, a centre-midfielder by trade, as a central striker.
Now, however, with the arrival of Bale and Vinicius, he has two top-quality backups at his disposal.
The pair showed their worth against LASK on Thursday night, and seemed to have an instant connection as they played in a front three with Lucas Moura out on the right wing. Eric Lamela, who is also more than capable of playing on either wing, was employed in a central midfield role.
Vinicius had a fine game on his Tottenham debut, setting up the opening goal of the game with a clinical pass through to Moura, who slotted home to open the scoring.
