Celtic will finish bottom of their Champions League group once again and it is pretty clear that they need to add some quality to the squad if they are to make any progress in Europe. Brendan Rodgers' side have put in decent performances but have not been able to get results. The addition of experienced and established players, who are ready to make an impact from the get-go, might help in that regard.
One area where Celtic might need to strengthen is left-back. To be fair, Greg Taylor has improved as the season has progressed. But it is pretty clear that Alexandro Bernabei does not have a future at the club unless something unexpected happens.
Over the summer, there were rumours linking Celtic with a move for Kieran Tierney. While the Scottish international did leave Arsenal, he ended up moving to Spain and joined Real Sociedad on loan.
His long-term future at Real Sociedad remains up in the air though. And it looks like Celtic might still be in the race to sign Tierney, although there are a few hurdles they will need to overcome.
Tierney would love Celtic return but there's one issue
As reported by TEAMtalk, Tierney will leave Arsenal permanently in the summer and a move back to Scotland is on the cards. Real Sociedad are unlikely to agree on a permanent deal for him. There is a belief that the Scottish left-back would love to return home but he is still just 26 and would like to keep playing at the top level for a few more years.
Someone like Tierney would be a fantastic addition for Celtic. But they would still need to agree a deal with Arsenal, who shelled out a £25 million transfer fee to sign him in 2019.
At the same time, while it looks like Tierney is open to a return to Celtic eventually, he appears to be keen to keep playing in a top five European league for a while longer. So, all things considered, do not expect a return to materialise in the near future.
