The England youth international impressed in the role against Blackpool.
Rose told the Spurs website: "It has been frustrating, I don't mind saying that, but I'm glad the gaffer put me in on Saturday. He pulled me on the Monday and told me I'd be starting.
"Left-back is not my natural position, but when you look across the midfield it's going to be hard for any young player to break in with the likes of Luka and Sandro in there, Tom coming back from injury and JJ being on the bench.
"But the gaffer's told me I've got a chance of playing a few games at left-back, so I'm happy to do that."
