Celtic left-back Kieran Tierney is living the dream at his boyhood club and is riding high.

The £25 million rated star is heading towards the pinnacle of his career and has a high ceiling which he will most likely reach.

This being said, the Scotland international hasn’t really been challenged since his introduction to the team.

However, these three left-backs are the types of players that next season’s boss should look at.

The first player that the Hoops should be watching is former target and ex Dundee United man Barry Douglas.

The one time Scotland international was highly rated but he went off grid to Poland with Lech Poznan.

After a few years, he moved further away to Turkey with Konyaspor before joining Wolves.

Now, the 29-year-old Glaswegian is with high flying Leeds United, playing 26 times this season.

He has two years left on his current deal with the Championship side but his age could lower a potential fee.

His best ability is his crossing and this is something that is sorely lacking in the Celtic squad.

Hoops should look to surprise Europa League outfit

The Bhoys must look towards this season’s surprise Europa League team, Rennes.

 

The French side got as far as the last 16 and were knocked out narrowly by Arsenal last week.

However, in this campaign, the auxiliary defender Ramy Bensebaini stuck out like a sore thumb.

The Algerian is a similar player to former Hoops star Charlie Mulgrew and is an aerial threat in front of goal.

Unfortunately, Bensebaini isn’t known for his set-piece abilities but is the towering and ample defender Celtic need.

The 23-year-old’s contract is up at the end of the season and the Hoops would be doing a good job by signing him on a free.

Also playing last Thursday at the Emirates on the other team was Nacho Monreal.

The 33-year-old played in a back three against Rennes and dealt with the French side’s fierce attacking threats.

The Spaniard is an experienced defender and has played at the highest level.

However, due to his age, it would be surprising if another big money team come in for him.

His campaign this season shows he can still do a job for a club and Celtic must pounce on him immediately.

It would be ballsy but it would all boil down to whether the defender wants to move north.
