Brown had made just one appearance for the Black Cats this season, prior to his recent inclusions, but he has taken his opportunity with both hands.
The former Manchester United man has looked robust and disciplined during his time in Sunderland’s first team, and Allardyce has been impressed by the 36-year-old’s efforts.
“I have been delighted with Wes in the last two games,” he said. “I have to say he has proven the use of his experience and knowledge to be very good in the last two performances.”
Brown is entering the twilight of his career, but if he continues to put in performances of such high quality he looks set to remain in Sunderland’s starting line up.
The Black Cats have been porous throughout the season so far, but they have looked much more secure in their last two matches - which have resulted in a 1-0 defeat to Liverpool and a 3-1 win over Aston Villa.
Allardyce’s men’s victory of Villa was particularly important, as it moved them much closer to safety.
Sunderland are now just four points away from 17th place, with their next league match coming against fellow strugglers, Swansea City.
