Despite one newspaper saying he will face a 'hate mob' at Elland Road on Saturday, Glenn counters:
"Lee grew in stature as a player in the time he was there and he became an England player, so Leeds will always have a special place in Lee's heart - and rightly so.
"It is an important game for all of us but there is an extra 'specialness' for Lee who had, I believe, six and a half years at Leeds that were successful ones.
"It was the first club that he moved to after coming through the ranks at Charlton and it was a club that had a squad full of talent that became a Champions' League team.
"Lee learned in that environment and because of that he is the player that he is today.
"But the rest of us must make it special for us as well - because there are a vital three points at stake."
