4) Carlos Tevez | West Ham
Carlos Tevez joined West Ham, along with fellow Argentina international Javier Mascherano, in August 2006.
It took him until the following March, when the Hammers already looked doomed to relegation, to score his first goal for the club - in a dramatic 4-3 defeat to Tottenham.
Tevez went on to score six more goals for the east London outfit that season, including the winning goal against Manchester United to keep West Ham in the Premier League.
He performed miracles in those final two months of the 2006/07 campaign - and will always hold a place in Hammers' folklore.
