The good thing about being a pundit now is you have ex-footballers together and there's good banter. That's what it was like in the dressing room every day.
I've always liked the abuse on the football field. It inspires me, makes me feel better, I thrive on it.
Everybody sees the person on the football field and has a perception of him, but in the media or on Twitter it's just me being myself. I'm an honest, hard-working guy who likes a laugh.
Some of the things I've done, like getting Justin Edinburgh sent off in the cup final by going down, I'm embarrassed - I cringe when I see all that.
People say I'm attention seeking by coming off the Twitter, but that's not the case. If I wanted to attention seek I could drive my Lamborghini to the Trafford Centre in my underpants.
What you don't realise when you get injured for a long period of time is that it's so hard to get back. You see the lads out on the training ground and you're in every day - 8 to 5 - and it's horrendous. So when you actually come back it's a proud moment.
When I see Wales qualifying for the Euros and Leicester top of the league, I wish I was still playing.
To be given the opportunity to talk football with the best players. I'm a fan, so even when we're not on air, we're still talking about football. I love it.
I didn't make it at Manchester United because I had no choice, I wasn't good enough, but I was lucky enough to go elsewhere and have a career.
But one thing I do is I know my football. I watch leagues from all over the world, I do my homework and I love football and could talk to you all day about it.
I wasn't confident at all as a boy and I'm still not now. I'm one of the shyest people you'll meet. My success at football was down to playing with my brother and his mates in the street.
You only realise when you have children of your own how much your parents do for you. My dad, Colin, would get off work at 5pm and take me straight out and all over the country for football matches.
I've only had to choose between family and career once before, when Vancouver Whitecaps wanted to sign me. I didn't want to take my kids out of school so I didn't go.
A club steeped in nearly 150 years of history is worth more to the local community than any amount of money can express.
I love it, I love the coaching - at 15 they listen, they learn and take things on board and if they don't there's always someone else who wants that opportunity.
I even do things sometimes just to get the crowd booing me, whether it's smashing someone or doing something deliberately silly. It's been part of my game for a long time now.
I've had people spit in my face. I've had bottles thrown at me. My house has been attacked. I've had loads of things happen. People have written to me saying they are going to find me.
I'd rather be at home with my family anyway. I'm a completely different person there than on the football field. Ask anybody who knows me. They will all say I'm one of the nicest people you could ever meet.
Listen, the way I am, I'm never going to please everyone. But I wouldn't change a thing. There are ups and downs. But overall life is great. I love being Robbie Savage.
One of my most treasured possessions is the letter my father wrote to me when I left home to join the Manchester United Class of 92.
For many dads, pride is often defined by events like graduations, weddings or taking their sons to their first match.
Remember success never comes easy and on the journey you will make mistakes, win some and lose some, get some things right and wrong. But always keep in mind that it is not about how many times you fall down - its about how many times you get up after falling.
Never - and I repeat, never - let anyone tell you your worth, tell you that you cannot do something or determine what is good for you.
Look at all of United's successful teams under Sir Alex Ferguson and their captains were all big personalities: Bryan Robson, Steve Bruce, Roy Keane, Rio Ferdinand, Nemanja Vidic. You would follow them all into the trenches.
And I know the risks of changing captaincy midway through a season. At Derby, it was a great compliment when Paul Jewell handed me the armband, and I was made captain of my fourth Premier League club, but it was awkward for Matt Oakley, who had it taken away from him.
We cannot have Derby County going the same way as Macclesfield and Bury. That would be a stain on English football. It simply cannot be allowed to happen.
I played professional football for 21 years, captained four clubs in the Premier League and won 39 caps for my country.
But helping to raise a football club from the ashes, and running it as director of football operations, is the hardest thing I've ever done by a million miles.
When my business partner Rob Smethurst rang me up and said he wanted to rebuild the club as Macclesfield FC, and to bring me on board as his director of football operations, I thought he was mad.
With respect to the super-rich Saudis taking over at Newcastle, they are likely to bring success to a famous football club by throwing money at it.
Wading into a sell-out 3,500 crowd to separate hooligans throwing punches is not what I expected as director of football at a phoenix club.
Kids who dream of reaching the top must grow up looking forward to the big games which define them at every level they play - from Sunday morning in the park to non-League, the top four divisions, Europe and the World Cup.
There is minimal scientific evidence to suggest the Covid-19 virus is transmitted on football pitches in fresh air, so let's not play roulette with our young people's physical and mental well-being any longer.
I believe sports minister Nigel Huddleston, Secretary of State Oliver Dowden and Health Minister Matt Hancock all recognise the importance of kids playing recreational sport.
It is not my intention to break up teams at local grassroots clubs - but to make sure every kid gets an opportunity to play football for free.
Lockdowns have denied hundreds of thousands of kids access to football and, with no organised physical activity as an escape, some are becoming addicted to X-Boxes and Playstations.
I'm a campaigner for grass roots because I am a product of the grass roots system and I would like every child to have the same opportunities I was lucky enough to enjoy.
With games being called off, and clubs having to field under-strength teams because of Covid outbreaks, it looks terrible when pictures emerge of Premier League players enjoying social gatherings in blatant breach of the regulations.
