West Brom legend Ally Robertson joked he wasn't happy to see Tom Rogic join the Baggies after his Celtic exit - because he is a Rangers man.
The Australia international left Ange Postecoglou's men at the end of the season following a trophy-laden nine-year stint at the club. He took a lot of time over the summer to decide on his next move before deciding to make the switch to the English Championship by penning a one-year deal with the club holding the option for a further year.
On his capture boss Steve Bruce described 'The Wizard of Oz' as a serial winner and a top professional who could prove to be a brilliant acquisition for his side. His success at Celtic speaks for itself and it is something Robertson hopes he can replicate for his new club. They are sitting in 21st position after a poor start to the season that has brought just one league win in ten outings.
