He told Chelsea TV: "It was different for us, a bit more like a game in the stadium with the fans. It wasn't full but to have them there changes it a little bit.
"In other countries they do it with the fans around all the time, in England it is very different, so of course it changed the atmosphere. At Feyenoord, I remember training was always open, always with three or four thousand people watching."
Skipper John Terry also remarked: "It was brilliant, we should do more of these days for the fans, it is great for them.
"There is a great turnout and the least we can do is go over and sign autographs and show our appreciation for them."
