Kris Boyd insists Rangers must strengthen while on top as he reckons Celtic will spend big this summer.
Just hours after Steven Gerrard and James Tavernier lifted the Premiership trophy to cap an unbeaten league season, Boyd reckons the hard work starts again.
The pundit believes Eddie Howe will want a huge transfer war chest if he is to come as Neil Lennon's replacement.
He insists the Rangers board will also have to bring out their cheque book again in a bid to reach the Champions League - and keep the title at Ibrox.
Boyd told Sky Sports: "You look at it and you say can you go and win domestic cups, can you keep the league title at Ibrox next season.
“In terms of Europa (League) it’s been excellent but everyone knows the Champions League is a step up. If Rangers can get into that the money they get will allow them to strengthen even more.
“The players have been fantastic this season but there will be areas Steven will be looking to strengthen, and that’s just part of the parcel, but big clubs can’t stand still. They will need to keep improving.
“That will be the message when Steven Gerrard and Ross Wilson sit down with the board; we need to keep striving to get better.
“Listen, Celtic will spend money with the reports of Eddie Howe coming in. Celtic will have to throw a lot of money at this to try and turn this around.
“Rangers are in a good position, they have players they can sell, but the one you can’t afford to sell is Ryan Kent. He has been excellent.
“If they can make that bit of progress and reach the Champions League it would be a massive, massive stride.”
