While Joe Cole has retained the captain's armband he first claimed when Paolo Di Canio and Steve Lomas were both missing from the team, and will wear it again on Saturday, Glenn says that Steve Lomas retains the club captaincy and is happy with the situation.
"Steve knows from me that he is clearly an important member of the team and squad and I need his experience both at club level and international level to be club captain while I am at the football club.
"There will be games where he is team captain on the day. Steve Lomas is very much one of those players that, whether he has got the armband or not, will play a captain's role in terms of talking to the players, encouraging the players, and organising the players at different times during the game.
"I just feel that the form Joe has shown just recently and the way that he has taken to the responsibility of leading the team, there was no need to make a change in that area.
"I had a quiet word with Steve Lomas on Thursday and explained the situation. He is a first class professional and his reaction is exactly what I expected.
"He is the first to agree that Joe has been magnificent in midfield of late and has taken on the role and responsibility of the captaincy very well."
In any case, says Glenn, he expects everyone out on the field to stand up and be counted.
"You want everyone to take the responsibility, play a full part in the role of the team, and sacrifice themselves for the good of it.
"We all get the same result at the end of the season; we all know that the goal is survival and we strongly believe we can achieve that aim.
"Anyone who has got any individual concerns at this moment are putting those to one side for the benefit of the team."
That includes Paolo Di Canio, who misses the visit of Sunderland but will continue training with the aim of making himself available for our next game, at Southampton on April 5th.
Says Glenn: "He won't take part in the game on Saturday. He will have another two weeks of training after working hard this week - and I am sure he will have a big part to play in the final seven games of the season.
"We have had two wins and a draw, we have been playing very well, and it is difficult to change a side on that run."
Don Hutchison is certain to make the bench, however, and Glenn adds: "He had 90 minutes in the reserves on Wednesday and I am sure he is anxious to play some part against his old club."
