Former gaffers Walter Smith and Stuart McCall have both called for substantial investment in the playing squad to make Mark Warburton’s squad more competitive, but Weir feels that any progress after four years in the lower years has to be taken slowly.
He said: “Obviously, we don’t like it, but there is a gap because Celtic have invested and they’ve been playing at a great level.
“You’ve got to do it slowly. You’ve got to do it through a process and by constantly improving players, the environment, the challenges you give the players, and the youth department.
“You’ve got to constantly try to build up the whole structure of the club and the whole infrastructure of the club. It’s a big challenge.
“I would never question Walter Smith or Stuart McCall or anyone who has been manager of this club because they’ve walked in our shoes, but we’ve got to deal with the situation we’ve got.
“I understand their reasons for saying money needs to be spent and it would be great if that was the case, but we’ve got to work within the parameters and what we’ve been employed for.”
