And he insists that he wishes the Hammers every success for next season - whatever decision is made about an appointment.
"I hope the club go on from strength to strength," he says, "and I hope that whoever comes in keeps the people at the club and looks after them."
He stresses that he bears no ill will to West Ham, adding: "What good does that do you in life?
"You end up getting bitter and twisted, looking at results wanting people not to do well, and I wouldn't do that.
"I want to see West Ham get in that top half of the division again, but I still believe quite firmly that they need to bring in two or three good players if they are going to do that; there's no doubt about it because it's going to be a tough league."
Harry says he does not expect to get a call from his successor asking for advice, and says: "They wouldn't do that I'm sure; whoever comes in will be their own man."
He hopes that the club continues to progress under the new man, and reflects: "Let's be honest, when I took over the club without being disrespectful, if you'd sold all of the players there you wouldn't have got £4m for the lot.
"And now, if the chairman wanted to sell on the players that are there today he'd be sitting on £70m or £80m of talent, there's no doubt about that - it's a gold mine of assets."
Looking back on the highlights of his Hammers' career he reflects: "I never forget going to Metz and turning the result around, beating Heerenveen, who came second in the Dutch league last year, getting into Europe in the first place and finishing fifth in the league.
"I'll remember playing the football we played that year when Berkovic was pulling the strings and there was fantastic movement all over the pitch.
"I'll look back on seeing the kids come through, and going to Old Trafford and Sunderland and winning only eight or nine weeks back.
"That was a great spell and I was offered a four year contract before Old Trafford that never did get signed; it was offered but it dragged on unfortunately.
"But that is done and dusted and I'm not going to make a fuss over that - these things happen.
"As long as people treat me fairly I'll be fair with them and I've got nothing but good to say about the people that I worked with - and worked for. Life's too short to make enemies.
"Those were terrific days, but everything went a bit boss-eyed after that with the Tottenham game when individual errors cost us.
"Then suddenly a few results with the Chelsea and Arsenal games before the cup and having Pearcey sent off and conceding a penalty against Everton....
"But it was a pleasure to work with Stuart Pearce and Nigel Winterburn, two of the best professionals I've seen in my life."
Harry admits that he has not got over emotional since his departure last week and reveals: "I'd be lying if I said it was too bad; that's how I am, life goes on.
"There will be a West Ham long after I am gone: there have been better people than me have left the club and there will be better people than me coming in in the future, so I've got no problems with that.
"I just hope whoever comes in is a good man and a good person and does well for the club - he will have some great players to work with."
As for his thoughts on manager number 9 being Alan Curbishley, he says: "I like Alan, he's a good lad, he's done a great job at Charlton, and I think he will be the first to admit that we murdered them twice this year.
"We murdered them by five at home and absolutely slaughtered them away from home.
"I'm sure he'd do a great job if he went there but whether he does or not, I don't know - that's for him to decide."
Harry does not think, however, that the next manager has to be a West Ham person, and adds: "Not necessarily - there aren't too many around these days.
"I don't know, I just hope they make the right decision and get someone in to do a good job. Whoever they choose, I wish them every success and I genuinely mean that.
"I haven't had a chance to say goodbye to any of the lads, but 98% of them were fantastic fellows, a pleasure to work with."
And the inside track on Frank Lampard junior?
"I don't know what Frank will decide to do; it's for Frank to decide.
"He is a great professional, he's his own man and he always has been, so I'm sure he will decide what is right for him."
