Defender Dean pointed out yesterday that a confident, in-form Beattie was as good a striker as there is in the Premiership.
Former Saints boss Glenn said: "Beats is a good player and I thoroughly enjoyed working with him.
"He was patient, broke into the side and he's come on.
"He has every attribute of an English centre forward. He's strong, good in the air, little bit of pace, works extremely hard and is a good team player.
"At the moment he's finishing off all his good work as well.
"He had a run like the one he's on now when I was manager down there. He's got to be watched."
Glenn Hoddle agrees with Dean Richards that Jamie Beattie will be the man to watch at Southampton this afternoon.
