Ravel’s come in and he’s going to be training with us for a few days so we can have a look at him. That’s it really.Harry Redknapp
The 24-year-old former Blues loanee has not figured for the Italian Serie A side since April, 2016.
More recently he spent the second-half of the 2016/17 season on loan with Sky Bet Championship side QPR, where he featured five times for the R's.
The forward made 30 appearances and scored three goals for Blues during the 2012/13 Championship campaign under former manager Lee Clark.
Blues boss Harry Redknapp said: “Ravel’s come in and he’s going to be training with us for a few days so we can have a look at him. That’s it really.”
Redknapp managed Morrison at QPR during his first loan spell there, and the former Manchester United trainee scored twice in their 2-0 win at St. Andrew's in March, 2014.
