Scotland assistant coach Peter Houston says recalled Sunderland striker Steven Fletcher isn't guaranteed a start in World Cup qualifiers against Wales and Belgium.

Speaking at Scotland's Mar Hall base on the outskirts of Glasgow, the Dundee United manager, ahead of Friday's game against Wales in Cardiff, was asked if there was now pressure to play Fletcher.

"Absolutely not," he replied. "Why would we feel pressure? It is a squad game.

"You pick a squad then you pick a team. You have two games coming up.

"I haven't spoken to the manager regards whether he is going to play or not.

"I think the biggest thing at this early stage is making sure everyone is fit.

"It might be that he is picked in two games, it might be that he is picked in one game, he might not be picked at all.

"It is something that has not been discussed.

"But to say there is pressure, then I would say no."
