Sinclair plays his old club today and told the Guardian: "The only 'foreigners' were the Scottish lads.
"These days the Brits get outnumbered but, back then, Chelsea was a very British club. There were about seven or eight of us who had come through the ranks - the likes of Eddie Newton, Michael Duberry and Jody Morris - and it's incredible to compare the Chelsea of then and now. Just look at the ground. When I started it was horrible, an absolute eyesore. There was the Shed but it wasn't pretty and it was so far from the pitch the supporters needed binoculars to see what was going on.
"Chelsea used to be a lads' thing: have a few beers, go to the match half-drunk, then a big night out. The stadium was a dump and there was a lot of racism too, even directed at our own players. Nowadays the ground's fantastic and there are a lot of corporate people and families. It's the same club but in many ways it's different. It's the way football has gone."
