Adam Idah has arrived in Glasgow to complete his move to Celtic.

The Norwich City striker touched down at Glasgow Airport last night to finalise his loan from the Championship club.

The deal has progressed quickly since Tuesday evening when it was first reported the frontman was of interest to the Hoops.

The Republic of Ireland frontman will spend the remainder of the campaign on loan at Celtic Park, however, it will be a straight six-month loan - there will be no outright option to buy the player included in the agreement.

That's not to say if he performs well Brendan Rodgers wouldn't be keen to sign him on a permanent basis.

Idah will be drafted in to provide competition for Kyogo up top, as well as Oh, who is currently away on international duty with South Korea.

His loan will be completed at some point on Thursday, which is deadline day for the winter window.

He jetted into Glasgow around 11pm on Wednesday night. He could make his Hoops debut away at Aberdeen on Saturday lunchtime.

Meanwhile, for many Celtic fans, putting forward any sort of justification of their club’s transfer business this January amounts to defending the indefensible.

The late loan signing of Adam Idah from Norwich City – without an option to buy should he buck expectations and do well in Glasgow – has simply fuelled the notion that the window has not gone to plan, supposing there was a plan at all.

Manager Brendan Rodgers, given his own openness about his desire for at least four quality additions in the winter window, would perhaps be the last man you would expect to amount a public defence of such short-term thinking.

But he appears to have developed a degree of realism in recent days, something it could be argued has been browbeaten into him by the disappointments of his two transfer windows since returning to Celtic.
