Danny McNamara made the most of his St Johnstone loan spell from Millwall.
Now he is backing fellow Lions defender Hayden Muller to shine at McDiarmid Park this season.
Centre-half Muller recently arrived in Perth and played 30 minutes in Tuesday’s home friendly with Preston North End.
The 19-year-old looked comfortable on the ball and strong in the tackle as Callum Davidson’s men earned themselves a 1-1 draw.
McNamara told Muller that the move to Saints would be a worthwhile and enjoyable experience.
“It’s such a great club with a very good manager,” McNamara said. “Saints are getting themselves a good player.
“Hayden made a few first team appearances for Millwall towards the end of last season. He is so good on the ball, very calm and composed.
“Hayden is also good at one v one defending. He will be a real asset to St Johnstone, I’m sure. He is only 19 and he is still learning.
“I actually think he is good enough to play for Millwall right now but he might not have got as many opportunities as he’d have liked if he had stayed.
“Going on loan to St Johnstone and playing in the top league in Scotland will definitely help him progress.
“Hayden will find he is in a great dressing room. I know the lads will help him settle in.
“Obviously Gary Rowett thinks Hayden will be playing at a good standard otherwise he wouldn’t have sent myself and then James Brown there last season.
“Scottish football sometimes gets looked down on but I know how good it is.
“I really enjoyed testing myself against players like Borna Barisic and Ryan Kent at Rangers.
“But I was up against plenty of other quality players.”
McNamara was recalled by Millwall in January and went on to impress at The Den, picking up their young player of the year in the process.
His departure opened the door for Shaun Rooney, who went on to write his name into the history books by scoring in both cup final wins.
“I was jealous of the lads watching the finals on TV,” McNamara said.
“But Shaun is a great guy and no one was happier for him than me when he got those vital goals in the second half of the season.”
