He will spend close season on recruitment mission to increase selection options

Scotland manager Steve Clarke will attempt to use this summer to bolster his squad ahead of next season's European Championship qualifiers.

Clarke was disappointed but not disheartened by the performance in Belgium on Tuesday night when his new charges were beaten 3-0 by the No 1 ranked team in the world.

Now he will spend the close season on a recruitment mission to increase his selection options.

Scotland play Russia, Belgium, Cyprus, San Marino and Kazakhstan in the autumn – and Clarke has three players, who qualify for Scotland through their grandparents, in his sights to add to his options.

CHE ADAMS

The 22-year-old Birmingham striker would bring proven firepower to the squad.

Adams was a target for Middlesbrough in January but Birmingham rejected the bid. He also interested Fulham.

Birmingham are likely to sell the highly-rated front man in the close season and Clarke is aware of what he would bring to the Scotland set-up.

HARVEY BARNES

The 21-year-old Leicester winger is currently with the England Under-21 squad for the European Championship finals.

He can also play for Scotland and he will be sounded out about his willingness to play full international football for Clarke's men.
