Jose Mourinho said "my future choices are going to be very easy" after Tottenham's surprise 1-0 Europa League Group J defeat by Royal Antwerp.
Mourinho made four changes at half-time after appearing to lose patience with some of his fringe players in Belgium.
Dele Alli, Steven Bergwijn, Giovani lo Celso and Carlos Vinicius were all replaced at the break, although the changes did not salvage a point.
"I would like to have made 11 changes at half-time," said Mourinho.
England midfielder Alli, 24, has started three matches this season and been replaced at half-time in two of them.
