From January 1, Robertson is permitted to speak to clubs outside England about a pre-contract before a potential departure as a free agent in the summer. He is being linked with a return to Celtic and has previously stated a desire to join the Hoops while he is still able to make a significant impact. Former Hoops defender Kelvin Wilson said to Gambling.com at the Scottish Masters that it may not be the right moment for Robertson to join Celtic, following the arrival of Scotland teammate Kieran Tierney from Arsenal last summer.

Andrew Robertson, a 31-year-old Scottish defender for Liverpool, is reportedly open to a pre-contract agreement with Celtic for a possible Bosman transfer next summer. TEAMtalk has reported that Robertson is willing to rejoin Celtic, where he had a spell as a teenager, in 2026. It is claimed that a free transfer to the Bhoys is a possibility next summer, and that Robertson is open to agreeing to a deal when the January transfer window opens in the New Year. The defender joined Liverpool in July 2017. His current market value is €15.00m, according to Transfermarkt. For Scotland, he has 88 caps and has scored 4 goals. This season, Robertson has made 5 appearances in the Premier League and has not registered a goal or an assist. He has also been linked with Atlético Madrid.
