Everton manager David Moyes admits it is "sad" his club have not been able to keep pace with the progress made by Tottenham.
While Tottenham have built on their Champions League debut last season and can move within three points of Barclays Premier League leaders Manchester City with a win on Wednesday at White Hart Lane, Everton are mid-table and 18 points behind their hosts.
And Moyes, who remembers a time not so long ago when the two clubs were battling it out for European qualification, knows counterpart Harry Redknapp has benefited from having access to one thing he has not - money, and said: "It is a little bit sad they are starting to pull away from us a little bit more than I would like."
He added: "I think it was only three or four years ago us and Tottenham were competing neck-and-neck for European places.
"It is frustrating because all managers will tell you when you are close and competing with teams you never like to see them go away from you, but we are looking at them going away from us at this present time.
"Tottenham, arguably, might be the biggest spenders in the Premier League - they have always supported whoever the manager has been.
"Football will always come back around sometime and some day hopefully they will be looking at the back of us. At the moment it unfortunately looks as if you need a bit of finance to get it back, but it would be nice to think we could do it the way we have done it.
"We will work really hard and try to bring in players, produce our own players here, work with them, develop them and try to make them better.
"That is how we do it at Everton, we don't do it any other way."
