Chelsea boss Jose Mourinho says 36 year-old Didier Drogba was the difference in their 2-1 Capital One Cup win at Shrewsbury Town.
The striker fired in his third goal in as many games as the Blues edged into the Capital One Cup quarter-final with a 2-1 win at Greenhous Meadow.
Jermaine Grandison's late own goal won it following Drogba's opener, which followed the Ivorian's strikes against Maribor and Manchester United in the last week.
Mourinho said Drogba was an example to his squad after his key impact.
He said: "Yes I was worried when they equalised but we go through and Didier played a massive part in that.
"Hopefully he will be good for the weekend but we will have to see because right now his character is stronger than his body.
"Maybe what he has done today is through his character - not his body.
"That's what makes players special and any of the young players lucky enough to play alongside him, learn from that."
