Rangers may not be able to complete the signing of Calvin Bassey until August due to uncertainty over the opening of the Scottish transfer window.

The Light Blues announced last Saturday they had captured the left-back, 20, from Leicester City on a pre-contract agreement.

But Bassey does not become an official Ranger until the transfer window opens and the timing of that is up in the air even though the Scottish 2019-20 season was prematurely terminated last month.

World governing body Fifa allows individual associations to decide when to open and shut their transfer windows, allowing them to run in the summer for a maximum of 12 weeks.

But the Covid-19 pandemic and the late ends to most domestic leagues means new plans are being put in place for this year.

A league source has told Football Insider a decision is set to be imminent from Fifa that will authorise domestic leagues to open their respective transfer windows up to four weeks before the season finishes, some of which may not be until late mid August, which is when the later rounds of the Champions League and Europa League are being played.

It will ultimately be down to individual leagues to formalise their own dates within the Fifa guidelines.

In Scotland, that could mean the window opening either next month, or possibly not until the start of August.

Sky Sports notes that the FA in England is discussing proposals for a window that won’t actually begin until August when the domestic season is over.

Talks with other national associations across Europe are said to have already found “some consensus” over a transfer deadline of Friday 2 October.

Football Insider exclusively revealed on Saturday afternoon that Bassey was headed to Ibrox after rejecting a new contract at Leicester City.

Cross-border rules mean Rangers will only need to pay Leicester a fee of around £300,000, avoiding the need to pay the same compensation for development costs as clubs down south.

An attacking left-back who can also slot into central defence, the youngster has played extensively for Leicester’s Under-18s and Under-23s side and featured for them in the UEFA Youth League.
