Darron Gibson has told Everton's official website that he was left feeling tired after being his handed his first start of the season against Norwich City.
Gibson admits that he doubted whether he would be able to last 90 minutes in the fixture, but in the end he was required to play for 120 minutes, after the tie went to extra-time.
The central midfielder coped with the demands well, and he helped Everton to claim victory on penalties, to make it through to the quarter-finals of the competition.
And Gibson said afterwards: [I feel] stiff, in a word!”
“I wasn’t sure I’d get through 90 [minutes] but I got through 120 and I’m delighted with that. It shows how hard I have been working in training to be ready.
“I’ll be a bit tired for the next few days, but hopefully I can be involved at the weekend as well."
Gibson has missed most the season so far, with his only other appearance coming as a substitute in a Premier League match against West Bromwich Albion back in September.
The Republic of Ireland international's career has been plagued by injury, but if he can stay fit for a prolonged period of time, he could have a big part to play for the Toffees.
Gibson's energy makes him a valuable member of Roberto Martinez's squad, and he will be hoping to stay off the treatment table for the foreseeable future.
Everton's next match comes against Sunderland on Sunday, meaning Gibson has four days to recover from Tuesday's exertions.
