Lambert's decision to field Christian Benteke ahead of Bent was a surprise one given that the England striker had come off the bench to score a crucial equaliser against West Brom last week.
The Scot defended the decision tonight, saying: "Christian gives you a different option.
"Darren's threat is going in behind. That was the only reason why we did it.
"Tottenham's full-backs are going to bomb on at every opportunity so that's why I went with that decision. Darren has been fine about it."
