Christian Pulisic made a vital intervention for Chelsea on Sunday by scoring a last-minute winning goal against West Ham.
The United States international came off the bench to replace Timo Werner in the 76th minute of the Premier League clash.
The substitution proved crucial for the Blues in the end, as he went on to fire in the goal that secured three points for his side.

But Jorginho failed to convert the spot kick, sending it straight into the arms of goalkeeper Lukasz Fabianski.
Just as a draw seemed inevitable, Pulisic stepped up to make the difference when a pass from Marcos Alonso found him in space and he was able to fire into the net.
