Chelsea boss Di Matteo insists Cole winner always coming
But Di Matteo said: "I thought it was just a question of time before we scored.
"Obviously, when it comes towards the last 20 minutes, time is running out.
"But when you play against Stoke, it's always so hard to break them down and they defend with so many men and they're very well-drilled as well."
They failed to get Fernando Torres scoring but Di Matteo said of the £50million man: "He's in a very good mood because he's in a team that's at the top of the league."
