Martyn Margetson may hail from south Wales, but the blue half of Manchester is where he made his footballing home.

West Ham United's goalkeeper coach spent ten years with Manchester City, joining the club as a 16-year-old before going on to make his debut in a Manchester derby and 50 first-team appearances in total.

Margetson, who joined the Hammers in summer 2011 on the recommendation of the late Gary Speed, who he worked alongside with the Wales national team, is looking forward greatly to returning to his old club on Saturday.

The 41-year-old told he has been delighted to see the Citizens achieve great things following their move to the Etihad Stadium in 2003 and is hoping West Ham's switch to the London 2012 Olympic Stadium will bring similar success to east London.

Marge, we head to Manchester City in the Barclays Premier League on Saturday. Although the place has changed a bit since you left in 1998, it is still your club, isn't it?

MM - "Yes, it's definitely still my football club. I spent ten years at Man City from when I was 16 until I was 26 and theirs is still one of the first results I look out for and always will be. It will always be a special club to me, having spent so long there."

There are lots of similarities between Manchester City and West Ham United - traditional clubs with big, loyal fanbases. The City supporters have got their rewards in recent years with the FA Cup in 2011 and the Premier League title last season, haven't they?

MM - "Yeah, the Manchester City fans are a special bunch. I think it's well-documented that Manchester United have got a massive fanbase but it's all over the world, while a lot of Manchester City fans are Manchester people from around the local area. Like any city with two clubs, like Liverpool, families are either red or blue. It's an amazing rivalry and both sets of fans are amazing, but obviously the Manchester City fans are a super bunch and they got their rewards last year with winning the title and deservedly so."

When you look back at Maine Road and your old training facilities, the club has made a big transition to the SportCity complex and it has paid its dividends, hasn't it?

MM - "Maine Road was a great stadium and there was obviously massive tradition there but it was the right thing for the football club to move. It's similar to what we want to do here. They springboarded into the Commonwealth Games stadium and it's an amazing place. It's taken the club onto the next level, which is what West Ham are trying to achieve with the move to the Olympic Stadium. It certainly worked for Manchester City. Everyone gets a lift and the facilities are second-to-none and they got all the investment from the Middle East and it has taken them on. They've attracted world-class players and that resulted in them winning the title last year. It would be amazing if West Ham can emulate what Manchester City have done, taking on a new stadium and with a manager wanting to build and build and so on."

We hosted Manchester City in the reverse fixture in November and held them to a goalless draw, with Kevin Nolan having a 'goal' wrongly ruled out for offside. We are in good form, too, so do we go to the Etihad Stadium confident of getting a positive result?

MM - "It was a good performance at home. To keep a clean sheet against Manchester City is no mean achievement. I think it's the only game we haven't scored in at home this season, but it was a good game and we were delighted with a point - we'd definitely take the same result on Saturday!"

Martyn Margetson has worked closely with Jussi Jaaskelainen

One player who will be important if we are to keep a clean sheet is goalkeeper Jussi Jaaskelainen. You work more closely with him than anyone at the club, so what has been the secret to his outstanding form in recent months?

MM - "Jussi has been in a fabulous vein of form of late, which has been the result of the hard work he has put in all season. He has walked in the door and has been prepared to work his socks off on the training pitch and, if that is your work-ethic and your attitude then you will start getting your rewards on the pitch, which is he doing now. He is making important saves for us at absolutely vital times, which is definitely what you need from a goalkeeper. Sometimes you might need to have to make one or two saves per game, but if you don't have somebody who can make them, it can make the difference. Thankfully, Jussi is making those saves for us at the minute and he's been absolutely different class."

Even though Jussi recently turned 38, have you noticed improvements and changes in his technique since he joined the club last summer?

MM - "It's been difficult because, at 37 when he walked in the door, his technique and his style have been established over 20 years. But, to give Jussi credit, it hasn't been his way only. He has been open to different ideas, which we have spoken about all season. Every coach has different ideas and I have my own ideas, but to be fair to Jussi he has been approachable and I feel we've have a good working relationship. Hopefully, everybody is seeing the end results now."
