Crewe Alexandra boss Steve Davis says his four years at the League One club is a "big achievement" in the current climate.
Davis, 50, is preparing for his fifth campaign with the Railwaymen since replacing Dario Gradi in November 2011.
"It's a big achievement I think, it's something I'm very proud of and the four years seem to have flown by," Davis told BBC Radio Stoke.
"I've got no qualms about moving anywhere, I'm very happy at Crewe."
In his first season at Gresty Road, Davis took over after the club had made a poor start to the 2011-12 League Two campaign.
He won his first league game in charge at Morecambe and ended up taking the club to the final of the play-offs, beating Cheltenham at Wembley to win promotion.
Davis took the Alex back to Wembley the following season as they won the Football League Trophy with a 2-0 win over Southend and finished 13th in the table, 10 points off the play-offs.
|Steve Davis: Four years and counting|

|Only Jimmy McGuigan and Ernie Tagg, in the 1960s and 70s, along with the legendary Dario Gradi, who oversaw 1359 games in four spells over more than 25 years, have served the club longer than Davis since the Second World War.|
Those successes were achieved despite Davis seeing some of Crewe's best players leave, with Nick Powell, Ashley Westwood and Luke Murphy sold to Manchester United, Aston Villa and Leeds respectively.
"The last two seasons have been very challenging - football's moving all the time," he added. "With the introduction of agents and what young players are getting paid, it's becoming very hard.
"The EPPP (Elite Player Performance Plan) has changed where young players go now and it's very hard to keep the better ones we've got and obviously your standard of player suffers down the line.
"But we're finding ways of improving and that's been key to what we've been doing in the summer."
Crewe, who have five new faces in their squad for this season, open their League One campaign with a home game against neighbours Port Vale on Saturday.
