Sunderland and Southampton went head-to-head at the weekend.
Defoe had started the previous 10 Premier League games for the Black Cats but he was on the bench for the vital clash with Southampton, coming on for the last 31 minutes and subsequently scoring a vital equaliser.
Speaking to the Echo, Allardyce said, “Jermain hadn’t scored since Liverpool, so we put Dame (N’Doye) up the top and he did a good job in creating chances.
“Jermain was disappointed he wasn’t selected but he went on and scored. He says, ‘There you go, are you going to leave me out next time?’.”
Defoe was scoring for fun earlier in the campaign, netting a hat-trick against Swansea City and a brace against Aston Villa to suggest he would single-handedly fire the Black Cats to safety.
However, prior to Saturday he had only found the net once since that memorable day at the Liberty Stadium and it was no surprise Allardyce sought to change things up.
That said, Defoe proved his worth and is likely to be back in from the start when Sunderland take on Newcastle in a huge derby later this month.
