The Parma midfielder had been highlighted through data analysis as one of a small number of players whose running numbers compared closely with Arne Engels.

With time running out in the window, Celtic had to move quickly after deciding not to continue with the Gineitis deal.

Sørensen then joined on a season-long loan from Parma, with Celtic also holding an option to buy.

The structure of the deal appealed to the club because it gave them a short-term solution without committing to a permanent signing after missing out on their preferred target.

Claims have since suggested Celtic could return for the Lithuania international in January.

Whether that happens remains to be seen, but the background to the Sørensen move shows Celtic had already spent time trying to bring Gineitis to Glasgow before changing direction late in the window.
