Alex McLeish has warned Birmingham midfielder Barry Ferguson he runs the risk of losing his regular spot at St Andrew's if he makes a return to international football with Scotland.
Scottish FA chief executive Gordon Smith has confirmed any successor to the sacked George Burley will be free to select Ferguson, who has been capped 45 times. The former Rangers captain was no longer considered for international duty following incidents when on duty with his country last season.
But McLeish believes coping with the demands of the Barclays Premier League and international football at the age of 31 may mean him having to rest or rotate Ferguson on occasions, and he said: "Would Ferguson welcome a return to playing for Scotland? I don't know but, if Barry was asked the question, he would be needed to be reminded he is in the Premier League and you need legs in this Premier League. If you are going to play every single game, you need to be super fit."
He added: "To go and play international football at the age of 31 and to come back and perform week in and week out for us may mean there are times I'm going to have to rest or rotate him.
"He will have to consider that side of things. Am I being selfish? No, I am just guiding and educating him."
Ferguson will return after suspension for Saturday's home clash with Fulham. He missed the 2-2 draw at Liverpool after being sent off for two bookable offences in the previous encounter with Manchester City.
McLeish believes Blues have set a standard which needs to be maintained in their last three games and has warned against complacency.
He said: "We have intensified training this week and we are looking for the players to get back to the same kind of tempo, the same kind of performance level of recent weeks.
"They have set the standards now and we will be demanding that type of performance from them every single week and they are capable of doing it.
"They have improved but, if they get complacent, they know what happens so it is up to the coaches and myself and the leaders in the team to keep on top of people and make sure that no-one is slacking."
