Fox outlines plans for Villa
Chief executive Tom Fox believes Aston Villa can close the gap on the Premier League's leading clubs, but has warned their rise will take time.
Villa issued a statement of intent over the weekend after tying England midfielder Fabian Delph to a new four-and-a-half year deal.
They have battled relegation for the past three seasons and American owner Randy Lerner, who has scaled back his investment, put the club on the market last year.
Fox, a former chief commercial officer at Arsenal, is keen to build Villa's off-field profile to boost their revenue but acknowledged the club must be patient and not rely solely on Lerner's investment.
He said: "The game has changed significantly and financially it has moved on considerably.
"The top five clubs from a revenue perspective are in a fairly different place to where we are now.
"I think top five is going to be very difficult for us in the period of three to five years, b ut we can get much closer to them in five years' time.
"Ultimately we want to get ourselves back into a place where we can at least see those clubs and be within touching distance of a maybe a place in Europe.
"Our chairman has never been afraid to spend money on the club b ut it is not sustainable. And under the current regulations it is not allowable for an owner to come in and put all of the funds in that are necessary to compete at the top of the Premier League.
"We need to put the club in a better position though to be generating more of its own revenue.
"This is a big club and we need to be capturing more of the value from being Aston Villa Football Club than we are today.
"If we do that it takes the pressure off the owner to put nothing but his own money in, which he has done significantly since he purchased the club."
Meanwhile, Andreas Weimann believes the signing of Delph shows Villa are moving in the right direction.
Delph, whose previous contract expired at the end of the season, admitted he never considered leaving Villa on a free and wanted to repay the faith shown in him since he joined six years ago.
Villa are three points above the Barclays Premier League relegation zone after just two wins in their last 18 games ahead of Sunday's trip to Arsenal.
But Weimann believes keeping Delph is a sign of a brighter future.
"It's what they're trying to do: keep the players here, build on it. And with Fab staying it'll keep us going," said the striker.
"He's not scared of anything. You see that in the way he plays, he's a really big player for us getting on the ball and keeping us moving.
"He showed it for England and us and we're glad he's staying."
