RANGERS' summer transfer business had to be wiser. 

That's the opinion of former Gers striker Kenny Miller.

The Scottish football pundit insists questions must be asked of the ins and outs at Ibrox over the most recent transfer window.

Seven new players arrived, including the likes of Antonio Colak, Tom Lawrence and Malik Tillman. 

Some have enjoyed a better start to life as a Gers player the others, with Ben Davies and John Souttar recovering from injuries. 

And Miller reckons the criticism aimed at Rangers over their business is justifed. 

He told Clyde 1 Superscoreboard: "The recruitment side is getting a lot of scrutiny at the moment and there are reported figures of £12million that are not even anywhere near the team at the moment.

"Yilmaz, Davies and even Matondo, you throw those three players in - £4m, £6m and £2m if that's accurate - they're nowhere near the team at the moment.

"When you're recruiting in a summer, Rangers or Celtic, when you're spending that type of money, they have to be hits. They have to make an impact on that first team.

"At the moment, there's question marks over Davies - is he going to be the long-term partner for (Connor) Goldson and has he got the quality?

"Matondo we've seen in flashes but at the moment, he's not going to be a starter. Yilmaz, we've barely seen any of him.

"There's not been much evidence of if it's going to be money well spent. It might be a project but it's a lot of money spent on a project.

"You go on the other side, (Celtic) sign Carter-Vickers and Jota, and they're the same players, so are they going to make Celtic better?

"Well they spent their money and they've spent that money really wisely."
