The Leicester City boss knows the Arsenal player well from their time together at Celtic.
Rodgers worked with the 22-year-old for two-and-a-half seasons in Scotland and helped develop him into the elite level player he is today.
He’s set to manage a team against the left-back for the first time this weekend, with the Foxes hosting Arsenal in a massive English Premier League encounter.
With Leicester currently in third spot, six points ahead of Unai Emery’s team, the Gunners will feel they have to pick up some kind of result.
One the keys to Arsenal’s season will be getting their summer signings up to full speed and peak form.
Rodgers thinks that Tierney will improve the London side, even if it takes him a while to adjust to life at the club.
As quoted by The Daily Record, he said: “It can take time for players to adjust. You can’t just click your fingers and settle into another city, at a different club with new teammates, away from your family. It takes time.
“I’ve got the boy here with me at Leicester, Soyuncu, who had been here for six months before I joined the club. It actually took him a year before he actually got into the team. Now he’s doing very well.
“So Kieran will improve Arsenal with his quality. He’s got a massive heart and once he gets himself fully fit and adjusted to the life there he’s going to be a huge asset for them.”
A difficult start
Tierney didn’t have the most conventional of starts at his new club, arriving with injury and fitness problems that had plagued him throughout 2019.
That meant he didn’t make his debut until late September when he faced Nottingham Forest in the League Cup.
Starts against Standard Liege and Vitoria in the Europa League demonstrated what he can provide Arsenal with if given opportunities, registering an assist in each match.
Since then though Arsenal’s general form has dipped. The club have drawn all three of the matches he has subsequently started.
The blame for that is hardly falling at Tierney’s feet though. There’s real hope he can emerge as a consistent first-choice pick at left-back.
If Rodgers words are anything to go by, that’s far more likely than not.
