Rovers boss Tony Mowbray admits he was impressed with what he saw from trialist Charlie Adam, but says he won't rush into a decision on whether to sign the midfielder or not.
The former Scotland international midfielder linked up with the club last week for training whilst the rest of the squad was in Austria.
The 33-year-old arrives with a wealth of pedigree having represented the likes of Blackpool, Liverpool and Stoke City in the Premier League after beginning his career in his homeland with Rangers.
Available on a free transfer after the expiry of his contract at Stoke, Adam appeared for the second half in Rovers' pre-season victory at Barrow on Saturday afternoon and produced an eye-catching display in Cumbria.
“Charlie phoned me a few days ago and asked if he can come in and train," Mowbray explained after the encounter against the National League side.
“Nobody can question Charlie Adam's talent as he's been a top, top player for a long time. You could see a Premier League quality footballer on the pitch. He was a joy to watch.
"He knows a few of the lads and played for Scotland alongside Charlie Mulgrew, so it's no problem at all.
“One of our young players, Brad Lyons, picked up a groin injury yesterday and couldn't play, so I asked Charlie whether he wanted 45 minutes and he said he did, which is the sort of kid he is.
“We put him on the pitch and he did pretty well spraying the ball around," Mowbray added.
“You get high quality football when he has the ball at his feet. He can hit any pass he wants on the pitch really.
“Football's more than just with the ball of course, it's about what you do without it as well.
“We'll wait and see, we'll see how he goes in training next week.”
