Old Firm derby is platform for underfire Brown, says Collins

JOHN COLLINS has backed Scott Brown to prove his critics wrong by showing he is worth every penny of the £4.4million (€5.6m) Celtic paid for his services.

Brown was regarded as one of the brightest talents in the country when Celtic beat off competition from Rangers to land the midfielder in a record-breaking deal last summer.

However, the 22-year-old has so far failed to live up to that billing during his time in the east end of Glasgow, leading to discontent in some quarters regarding his contribution this season.
