Sunderland picked up a 2-2 draw with Liverpool at the weekend.
Kirchhoff was stationed in a defensive midfield position at Anfield, after he impressed in the same role against Manchester City last Tuesday.
The January recruit looked excellent against City, with his distribution catching the eye, but Allardyce says that he wasn’t quite as influential against Liverpool.
“Jan, not so much on Saturday, but certainly against Manchester City, showed the quality of his passing,” Allardyce said. “The fact we didn’t play as well against Liverpool may have been because Jan felt the pace a little bit.
“He was the mainstay of all that was good for us against Man City but I think he felt the pace of this game a little too quick for him because he hadn’t fully recovered from Tuesday night. He’s got a full week this week (to recover) and hopefully we can get a result against Manchester United and go on from there.”
Sunderland picked up a valuable 2-2 draw against Liverpool, after staging a late comeback in the fixture.
The Black Cats had looked to be slipping to a defeat, but late goals from Adam Johnson and Jermain Defoe rescued a point for the Wearsiders.
Sunderland are still four points away from safety in the Premier League, but their improvements in recent weeks have been clear to see.
The Black Cats’ next match comes against Manchester United on Saturday, where they will be determined to pick up a win, which will move them closer to safety.
