Glenn brought West Ham fan Kevin to Upton Park from Manchester City for what will be a maximum price of £300,000 - and days later was gone.
"It was a bit of a shock, especially for myself having just come to West Ham, but I would like to thank him for the opportunity otherwise I might never have got the chance," he says.
"I owe him that and wish him well in whatever he does.
"I realise there was pressure at the club and obviously being manager he was at the head of that.
"I didn't expect him to leave within seven days of me joining, but it has happened and I just have to get on with it after he gave me the chance to come back to West Ham."
As for his thoughts on Glenn's successor, Kevin is keeping his cards close to his chest.
"It is not for me to say; obviously the fans love him and of course he is a West Ham legend," he says.
"But obviously it is up to the board and Trevor and everyone else at the club - it is not up to me.
"We are just trying to work hard for each other and obviously Trevor has been in charge for two great results so we will have to wait and see.
"We have had two great results and we have a nice little break now so we need to recharge the batteries and try to keep on winning - there is nothing better than winning."
As Kevin has retired from international football he has time to digest his change in circumstances in this international fortnight, and he adds:
"Now I have got a bit of time to time to realise that I have come back to West Ham because I have a lot to do with kids' schools to find and it is going to be a hectic week - but then I can look forward to the games ahead."
He admits that the Rotherham game, the day after which Glenn's contract was terminated, was a poor show, and he adds:
"I think we all realise that at Rotherham we let a lot of people down including ourselves and of course the fans that made the journey.
"I think we did that in the last two games; it has not been pretty at times but it is all about results in this division if you want to get out of it."
As for the dressing room 'furore' surrounding the trip to Millmoor he insists:
"It was all over the top and nothing to do with anything; at the end of the day we decided to get changed at the hotel and that is that.
"It is nothing to do with being 'Big Time Charlies' - we are the opposite if anything; it is all paper talk and you can't believe everything you read in the papers.
"They will go out there and scrap with the best of them."
At least the trip to Ipswich - and you couldn't swing too large a cat in their dressing room, either - he adds:
"We knew it was going to be very difficult but it was a good test for us and I thought we coped very well.
"We weren't really worried about what Ipswich did - and perhaps they were a bit unlucky - it was about ourselves.
"We did a great job, we defended well, but any team is going to have to against Ipswich."
Kevin had a more defensive midfield role at Portman Road and he has also played left back this season.
"I prefer the midfield role but I just want to be playing and if you are you can't complain," he says.
"Rob had the injury so I did it as best I could on Saturday, being asked to sit in a bit deeper, which is what I tried to do although it stopped me getting forward a little bit more.
"But there is Michael and Matty to do that so I was just pleased with the result and I don't care if I score or not.
"But I got one, the deflection!"
Yes, Kevin can reveal that it was he who deflected Wright's shot into the net for Ipswich's goal.
"I don't think it was going in, I think Jamo had it covered, but it just hit me and I couldn't do anything about it.
"It gave them the lifeline late on but I thought the back four defended magnificently; they were putting balls into the box but we coped well with it."
Kevin has soon got the measure of the place and insists that, despite there being so many new players at Upton Park, they are gelling together nicely.
"The lads are brilliant; I have settled in really well and they are a great bunch of lads."
He admits that his home debut nearly passed him by, though, and says:
"It was strange; the first home game happened so quickly that I didn't have time to dwell on it and take it all in but I am certainly enjoying being here.
"I have got a few mates that follow the Hammers and they give me a bit of stick now and again but I am just happy to be able to help a little bit getting this club back where it belongs."
