Chelsea defender Antonio Rudiger believes their work on the training ground was key to his opening goal against Leicester City on Saturday.
The Blues ran away with a 3-0 win against the Foxes in the Premier League.
Rudiger scored his side's first, with N'Golo Kante and Christian Pulisic sealing the win.
He told the club website: "I felt very confident going into this game and I promised my son that I will score. I helped the team have a good very good performance and it could have been even more.
"I like to get myself on the scoresheet but I take as well the clean sheet, because this is what makes me much happier. Overall we had the very good performance, we came straight out of the block strong and with good mentality."
