Arsenal captain Cesc Fabregas admits he's thrilled to see Tomas Rosicky fit and playing again.The Czech's mental fortitude during his 18-month spell on the sidelines helped Fabregas through his own four-month lay-off last term and brought the Arsenal squad closer together."Tomas Rosicky is probably one of the best friends I have, and he's been injured for nearly two years," Fabregas told arsenal.com."It's great to have him back and I'm really happy for him. I have learned a lot from him as well - to be strong and keep believing. He believed in himself, that he could play football and it is great to see him play."I was with him every day, I went to his house - it's like that. And I think team mates, we have to be like that as well. It was nice when they were coming to me [when I was injured]; it's nice now that I go to them."The important thing is you don't do it because you have to; you do it because you really want to do it. And I think that [at] Arsenal, there's this feeling with everyone. It's really good."
