Joseph Yobo admits he would not wish for the circumstances in which he is likely to replace Phil Jagielka in Everton's FA Cup final team.Jagielka will miss next month's Wembley showdown with Chelsea after suffering a cruciate ligament injury against Manchester City on Saturday.The defender faces at least six months on the sidelines and Yobo concedes it is a major setback to lose the influential England international.Yobo, who has started the last two matches, is now likely to play alongside Joleon Lescott against Chelsea providing he suffers no further injuries."I wouldn't want to play because Phil is injured, they're not the circumstances I'd like," said Yobo."I've been injured myself this season and I'm just getting back. I played alongside Phil against City and was in at Chelsea."For me it was a good comeback, but to lose Phil is difficult."Who is going to play now depends on the manager, but for me I think I made my own case against Chelsea, so the final is going to be very interesting."The Nigerian added: "I've been there. It's always hard to get back in, but I think the manager was trying to give everyone a game this time."I didn't play in the semi-final, but got my chance against Chelsea and I think I took it, but this is football."You can take it when you're out because you're not playing well, but with injuries it's not fair."That's what's been going on for me this season and now it's happened to Jags, so we're disappointed."
