Indeed, the former Premier League boss appeared on football highlights show Match of the Day and was discussing Villa's 2-1 loss at Crystal Palace.
Scott Dann scored Palace's opener, outjumping Clark, and Big Sam feels the 25-year-old should have done far better in the air against his opposite number.
Allardyce may have been more Mike Bassett than serious pundit for most of his analysis but, here, he took the Aston Villa man to task.
Allardyce told Match of the Day: "The determination of Scott Dann is good but Clark is marking him too tight, he lets him get a run on him, lets him get a touch.
"Clark should have done an awful lot more to stop Dann."
However, Big Sam was impressed with 19-year-old Villa youngster Adama Traore, who set up the own goal that briefly drew Tim Sherwood's side level with Crystal Palace.
He added: "He made a good impact when he came on and leaves [Jason] Puncheon for dead. There may be a bright future for Villa with this young man coming from Barcelona."
Developing sooner than expected?
Traore's instant impact was an interesting outcome considering Sherwood's firm warnings that Villa fans will have to wait to see the best of the teenager.
He may have had a bit of luck but Traore has already contributed more than some of Aston Villa's other signings, while the impressive Jordan Amavi ironically erred for Palace's goal.
