Nasser Hussain has hinted he may consider retirement after leading England to a seven-wicket victory in the first Test against New Zealand.
"Today at Lord's might be a good day to be your last," Hussain told BBC Sport after an unbeaten 103 at Lord's.
"I've got to go home and speak to my dad, see what he thinks and see what Nasser Hussain wants to do.
"There's a lot of soul-searching and a lot of thoughts to be done in the next 24 hours."
Hussain's 14th Test century was his first ever in the fourth-innings of a Test.
He described the experience as "one of the more enjoyable days of cricket I've ever had."
Hussain, 36, added: "To do it at Lord's with the crowd, to win it for England, to walk through the Long Room, it is a boyhood dream."
However, Hussain's spot in the XI was placed under pressure after Andrew Strauss struck a first innings century, making his debut in place of injured skipper Michael Vaughan.
In the second innings, Hussain shared a century partnership with Strauss, although he was responsible for running the debutant out for 83.
Nevertheless Strauss, who gained the man-of-the-match award, was overjoyed after playing a key part on his home ground.
"I'm running out of words to describe the last few days," he said.
"To play a Test was fantastic, to score a hundred was unbelievable and to win was even better.
"I've enjoyed every moment, enjoyed scoring runs and being part of a really good victory."
Stand-in captain Marcus Trescothick paid tribute to Hussain, saying: "To have him and Graham Thorpe at the crease made a huge difference.
"It was a tough time to come in but he showed the experience he's got," said Trescothick, who was already out when the former skipper joined the fray at 35-2.
"It was a pretty tough wicket and they bowled well but it was really nice that we've seen them off easily."
