The former West Ham ace fired Chelsea’s winner in the Champions League semi-final first leg at Stamford Bridge.
Cole said: “We’ll see how important my goal is next week.
“We’re not going to get over-excited – you saw that from the reaction of the lads at the end. It’s only half-time.
“We did well, but they fought back well in the second half.
“Both teams have improved form two years ago.
“This is the first time we’ve scored against them in Europe. Maybe this will open up the floodgates a little. Who knows.”
