Captain Jonny Howson feels he will not truly savour occasions like Middlesbrough's Carabao Cup semi-final, first-leg win over Chelsea until he finally ends his long career.
The 35-year-old midfielder was a key figure in Boro's 1-0 win over the Premier League side on Tuesday.
Yet, Saturday's Championship trip to Millwall is already in his thoughts, despite a special Teesside night.
"You listen to ex-pros say they wish they enjoyed it more," Howson said.
"But when you are professional it is hard to properly enjoy it. It's a great moment, it will live long in the memory whether you're starting out or the back end.
