Charlie Albinson has spoken of his delight at earning a contract with the club.
The 20-year-old goalkeeper has signed a one-year deal with the option of a further 12 months after impressing on trial.
The young shot-stopper, who was on the bench for the Under-23s' 5-1 victory over Wolves at Ewood Park on Monday night, said: "I'm really delighted.
"It is a big football club. Everything is really good here. The facilities are good, the staff are good and all the players have been welcoming, so it feels good.
"I spoke with Ben (Benson), the goalkeeper coach, a couple of weeks ago and I've been in the last few weeks training, getting used to things and it happened from there.
"Ben has been really good with me. The training sessions have been really good, he is very hands on and demands a lot from you, which can only help me improve.
"You have obviously got to try and impress when you come on trial, so it feels good to have been rewarded with a contract.”
Albinson had been on the books at Manchester City from the age of eight to 19, where he rubbed shoulders with some of Pep Guardiola's big names stars.
He insists he learned a lot from his time with the Premier League giants, but he is looking forward to an exciting new chapter in his career here at Ewood Park.
"I was there from a young age, so I've seen all the progression," added Albinson. "The facilities are amazing and the coaches and players there are unbelievable.
"I'd trained a couple of times with their first team. Their players are world class so you try to pick up little tips and learn from them.
"But the standard here is still very good. There are some good players here.
"The facilities here are very good, unbelievable for any club really.
"So the aim is to try and get as many games under my belt for the Under-23s, try to impress and work hard in training and see where it goes.
"I'm really looking forward to it. We are in Category One, so there are some big teams in there, so it will be good to test myself against the best Academies in the country."
