Journalist Pete O'Rourke has outlined the 'mistake' that Glasgow Rangers may have made in the summer transfer window.

The Lowdown: Seven new signings

The Ibrox outfit did make seven new signings in the summer, but also let go of experienced heads like Calvin Bassey, Joe Aribo and Leon Balogun (Transfermarkt).

They have reportedly been exploring the possibilities of signing Fabian Delph and Gary Cahill as free agents since the window closed, which suggests they may not have been completely satisfied with their business.

The Latest: Rangers 'mistake'

Speaking to GiveMeSport, O'Rourke has claimed that it was a 'mistake' by Giovanni van Bronckhorst's side not to buy an extra central defender as well as a goalkeeper:

“I’m sure most managers would look at the window, you’re not going to land all your top targets, that’s never going to happen, it just doesn’t happen that way in football.

“And I’m sure Van Bronckhorst thinks he should have maybe brought in another new central defender after losing a few with the likes of Leon Balogun leaving in the summer.

“Maybe not bringing in another central defender was a mistake as well as perhaps a goalkeeper because (Jon) McLaughlin has struggled in some games this season as well, while (Alan) McGregor is not getting any younger.”

The Verdict: Reinforcements needed

Given their start to the season, where they have lost 4-0 to bitter rivals Celtic and have also been defeated in both of their UEFA Champions League group stage games to Ajax and Napoli respectively, it is clear that the Gers need more reinforcements on top of the signings they made in the summer.

Cahill is still available as a free agent, and so would offer them that extra central defensive cover, but they could also do with upgrading the goalkeeping department.

McLaughlin has been criticised for some of his poor performances this campaign, while McGregor is 40 years of age and so does not have many years left at the top level.

Nonetheless, it could be a busier than usual January transfer window for the Light Blues.
