Snodgrass became the first signing of the Sam Allardyce era when he put pen to paper on an 18-month deal at The Hawthorns last week.
The former West Ham man is a close friend of Morrison, with the duo having got to know each other while regulars for Scotland.
A firm fan’s favourite, Morrison made 341 appearances for the Baggies after being snapped up from Middlesbrough in 2007.
Now, though, he is part of Allardyce’s coaching staff having previously spent time working in the academy.
And the 34-year-old believes Snodgrass is exactly the type of player Albion need as they bid to drag themselves out of the Premier League’s relegation zone.
“Snods is a great personality,” Morrison said.
“What he brings will click with this football club, what he demands.
“Ultimately, he is someone who can help this football club get out of the current situation.
“He’s the whole package. He’s been there and done it in the Premier League, he’s been in this situation before, and he brings a buzz around him.
“He’s experienced and he can help other people. He’ll push for better standards.
“We’re delighted to have him on board and we just can’t wait to get going because he hasn’t played that much football lately.
“He has a great delivery, he brings real energy, he can play in a number of positions.
“He’s a great addition to the squad. It’s key, particularly at the moment with Covid, to have a number of positions covered and Robert can do that for us.”
Meanwhile, the Express & Star understands Albion youngster Rekeem Harper has been made available for loan. A host of clubs in the Championship are believed to be interested in signing the midfielder.
