The 25-year-old has endured a difficult time of it following the recent death of his father but has remained impressively consistent on the pitch, most recently against Rangers in last Wednesday’s 1-0 victory.
Mjallby is surprised that the versatile Mulgrew is not yet a full Scotland internationalist although he believes the player’s chances might have improved after an extended spell at centre-half, an area where Craig Levein, the national team coach, could do with options.
“Unfortunately, he got a wee injury earlier in the season, but he’s back to his best,” said Celtic assistant manager Mjallby. “Sure, you can argue about his best position and it could be centre-half. He gives us great composure and he seems to read the game very well.
“It’s great to have a guy like Charlie,” he added. “He’s brought up in the academy, he’s a Celtic boy and he knows all about the club. He has a sweet left foot and is improving his defensive skills all of the time.
“For us, he’s been a sensation. I wouldn’t think Charlie would let anyone down with Scotland because, for us, he’s been terrific. The main thing for us is that he is doing well for Celtic, but I think he is definitely worth a look for the national team.”
