Harry Redknapp’s men were widely tipped to bounce back to the big time at the first time of asking, despite a disastrous 2012/13 campaign, which saw them finish rock-bottom of the division.
The club are also paying the price financially for the excesses of their foray into the Premier League, with their wage bill reportedly higher than that of La Liga champions and Champions League runners-up Atletico Madrid.
Fernandes says that this time around things will be different thanks to the harsh lessons his club have learned:
“Hopefully we’ll have some fun next year in the Premier League,” he told talkSPORT.
“It was great to see the kind of spirit we’ve cultivated in the club at Wembley, to see that passion from the team and the fans, it’s something I’ve always dreamed about.
“We learned so much last time [in the Premier League], you’re always learning really because even the big clubs make horrendous mistakes.
“We’re a lot smarter now and it’s been good for us down in the Championship, we’ve taken stock and been able to get the culture of the club right.
“We’re going to careful in the transfer market this time, we’re not going to rush into things. We’ve learned a lot [financially].
“We want to build the right culture at the club and bring in the right type of player and we want guys who are going to run and run and run.
“Derby showed that in the final, they had loads of young guys running around non-stop and causing a lot of problems for us. But experience also counts, you need to find a balance of both.”
