Newly-crowned champion trainer John Gosden admits defending his title next season will not be a straightforward task.
The Clarehaven handler finally landed the prize for the first time in his career after the curtain came down on the 2012 campaign at Doncaster on Saturday, beating Aidan O'Brien by a little over £160,000.
However, with some of his stable stars moving on, Gosden acknowledges he now needs to rebuild his team for next year.
"We're perfectly realistic about the fact that of the six individual Group One winners, four of them are retiring, so we know we have to build up again," he said.
"But that's the great thing about our business - young horses come in and it's like a process of regeneration. Just like a young squad to a football manager and a youth team.
"In 1997 I think I came pretty close to winning it (trainer's title), so it gives you a sense of satisfaction and fulfilment, but it also makes you hungry to get on with it in the next year or two."
The trainer has praised everyone in his huge Newmarket team after the triumph, including hugely-talented stable jockey William Buick.
Gosden told At The Races: "We've had some wonderful wins and won some super races in the last five or six years, but this year, with Aidan, it was tough. He won the first four Classics and was only just beaten in the fifth, but fortunately we had a strong team of horses and they stayed healthy and well throughout the year and ran consistently right through to the end.
"We have some fabulous owners who've been with us some time and we have a good team and good staff here. There's no sitting back, you work hard throughout the season and it's a great achievement. We have a very fine young jockey in William Buick, who rode half of those winners for us. It's a team effort.
"In the past I've been second, third, fourth and fifth in the title (race), so it's nice to win it. We had a nice party and we'll have another one at Christmas, which we do in proper style every year. From the night watchman to the work riders, everyone has put in a lot of work."
