Christopher Jullien was in action for Celtic against AIK at Celtic Park on Thursday.
The former Manchester United and Hibernian midfielder was impressed with the display produced by Jullien during Celtic’s 2-0 win against AIK at Celtic Park in the first leg of their Europa League playoff tie on Thursday evening.
Stewart told BBC Sport about Jullien: “As the game wore on I’ve been impressed, I think he’s got the attributes – he’s composed with both feet, good headers, positionally not too bad as well.
“Obviously there’s question marks because you spend £7m and he’s not playing a Champions League qualifier, but with Jullien from what I’ve seen I think he’ll be a good signing.”
Celtic were very good against AIK, and one of the reasons why they could keep a clean sheet was the performance of Jullien.
There were moments when the defender looked shaky, but the 26-year-old did look solid overall at the back and made some good interceptions.
Jullien joined Celtic from Toulouse in the summer transfer window for a fee reported by The Scottish Sun to be worth £7 million.
The defender did not particularly look great when he initially joined, but the Frenchman is getting better, and performances such as the one against AIK will only help him settle in better at Celtic and get the Celtic Park faithful on his side.
