Why?
Can't force players to sign, having targets and getting targets to sign for us is two entirely different entities. Most footballers won't commit to a £3k a week deal in Scotland if they still harbour hopes of getting £5+ a week in the overinflated English leagues.
Sometimes a bit of patience is required. Having watched the West Brom game it's clear that we're looking pretty solid, a couple of additional quality signings wouldn't go amiss however we have enough in the tank to go into battle.
