Scotland captain Darren Fletcher knows the Scottish Football Association need to think long-term in their search for Craig Levein's successor.

Fletcher, who has 60 caps, added: "Managers have gone on because they have achieved success for Scotland, and there have been managers who have gone on because they have maybe not.
"We are all disappointed Craig left, I think all the players would have liked to have seen him stay and continue his work and hopefully it could have come through on the pitch, but ultimately that's not the case.
"Just now we are working with a really experienced man in Billy Stark, who has been fantastic in the few days we have been together. He is desperate to do well and desperate to get a win."
Fletcher has been impressed with Stark in recent days, adding: "Although I don't think he will be expecting to be named a new manager, he will be desperate to get a good result and who knows what could happen.
"He has done great things from the under-21s and got a lot of respect from all the players and even in the couple of days that he has been in charge, a lot of players have been very impressed by him.
"If Billy could get a good victory and there is not a manager appointed before the next game, and we get another good victory against Estonia, then he really throws his name into the hat.
"It would be a choice backed by me but I'm not here to pick managers, I'm here to play for my country whoever is in charge and give them 100% commitment whoever the SFA decide to pick."
