Andy Murray is determined to be at his best for Great Britain's Davis Cup tie against Croatia after going out of the US Open in the third round.
Murray missed almost three months with a wrist inury
The Briton lost 6-3 6-3 2-6 7-5 to Hyung-Taik Lee on Saturday, and now aims to give Tim Henman a winning farewell at the tie on 21-23 September.
Henman will retire after the Davis Cup World Group play-off.
"I want to play my best, I'm going to fight until the last point," Murray told BBC Radio 5live.
"I'm not going to want to let the team down or let Tim down, I'd feel terrible if I was the one that was responsible for losing Tim's last tie.
"I'm sure he's going to be fired up for it, me and my brother are going to be fired up to play well in front of the crowd at Wimbledon.
"This means a lot to me and it's definitely going to be the biggest Davis Cup match of my career."
He added: "I'm sure it's going to be pretty emotional for everyone who's there."
Murray was out of action from 15 May until 7 August with a serious wrist injury and was upbeat on his efforts at Flushing Meadows despite the defeat by Lee.
"I've made massive progress," said Murray. "You've got to watch my matches in Cincinnati and Montreal - I wasn't moving well, I wasn't hitting my forehand properly.
"The confidence I've got in my forehand has gone up 10, 20 times, it feels so much better.
"Physically I think it was good for me to play a few tough matches.
"This has been a big step forward for me because it's been such a long time since I've been able to compete at the highest level."
