A transfer that was announced with snarling wolves, is looking increasingly like it may end with a whimper.
When Wolverhampton Wanderers turned to Diego Costa, it was done so with an air of desperation. The transfer window had been closed only three days when Sasa Kalajdzic suffered a knee injury which ended his first Premier League season before it was even started.
It meant that the Premier League strugglers had little choice but to look to the free agent market, with Raul Jimenez also struggling for fitness. Costa was quickly identified and was an option which very quickly got fans on board.
