Former Scotland captain Paul Lambert thinks an overhaul of the structure of Scottish football is required in the wake of Steve Clarke's resignation.

Clarke, who led Scotland to three major tournaments, resigned following the confirmation of Scotland's exit from the World Cup.

The 62-year-old penned a new four-year deal just before the start of the tournament in America, Canada and Mexico and even led Scotland to only their fifth World Cup win with a 1-0 victory against Haiti in their tournament opener.

But after a narrow 1-0 loss to Morocco and an error-laden 3-0 defeat at the hands of Brazil, followed by a lengthy wait to find out if they had managed to sneak through to the last 32, they hadn't, Clarke announced he'd be stepping down as Scotland boss.

"A little bit [surprising]," Lambert told BBC Scotland on the news of Clarke's resignation.

"He got us through to three major tournaments but I think what has disappointed everybody, in major tournaments we fell short.

"They [the players] will feel disappointed but I think they'll be disappointed in how they performed in the three games. They will look at themselves in the mirror and think "we never did enough" and I think that's the biggest disappointment.

"I think what Steve Clarke has done for the country is he's given us three brilliant major tournaments and nobody can knock it."

Now Lambert thinks, in the wake of Clarke's departure, a whole refresh of the Scottish footballing structure is needed, particularly at youth level.

"We focus on results which I think is all wrong for kids playing football," he added.

"We should be developing them as people and footballers. That has got to be looked at because we don't produce enough footballers for the national team.

"You can't get away from the fact that qualification for major tournaments is paramount but going deeper than that you've got to look at change to the whole Scottish football structure."
