Rangers' new owner Craig Whyte needs to spend money if he hopes to see the Glasgow club win further top honours, departing manager Walter Smith claims.
Speaking after the 5-1 win at Kilmarnock that ensured a third straight Scottish league title for the Ibrox outfit, Smith said his chosen successor, Ally McCoist, would need to bring in new players for next season.
"Unless there is a significant investment then the team will stagnate. They just can't continue to do what they have been doing at the present moment," Smith said.
"That is regardless of if I was the manager or anybody. Next season will be a problem. Hopefully, that will be looked at by the owners.
"But I don't think the new owner would have bought the club unless they were happy to put money into the team. The team needs a boost. He would be blind if he didn't realise that."
Smith has been operating with a smaller squad and tighter budget than during his first spell as manager at Ibrox, during Rangers' run of nine straight SPL titles.
Jelavic offers different option
However, last summer he spent £4million on Croatian striker Nikica Jelavic - a player who missed much of the season through injury but has provided a "different dimension".
Smith added: "I don't think Jelavic will leave this summer. I don't think it would be the brightest thing for the new owner to sell one of our best players - especially when everyone expects him to spend money.
"He just gives us something different up front - something we've never really had before.
"Kris Boyd could score, Kenny Miller could run through defences and, in the later stages of his time at Rangers, he was scoring a lot of goals as well, but Jelavic gives us a mix of everything.
"He can run through, he can link up, he can score and it has brought a different dimension to the team."
