The 30-year-old Swansea City loanee has started just a solitary game this term, which came against Stoke City in August.
He lasted 30 minutes against The Potters before he was stretchered off in the 2-1 home win.
Following an intense period of rehabilitation, the Ecuadorian winger has featured in Blues' last three games after coming on as a late substitute.
During those cameo appearances he has demonstrated his undoubted talent and given Blues an additional attacking outlet.
"He is a player who makes a huge impact in the games, specifically in what he does he is one of the best players in this league for that," said Blues' Head Coach Pep Clotet.
"He is a specialist, so valuable as an impact.
"Around him has always been a bit of concern with injuries and things, so we follow with him a very good programme to build up minutes after the injury he had.
"We keep following that - as you see now, he is coming on for longer and eventually it is going to be up to him to start games.
"There is nothing in my mind that says, ‘He can’t start games, he is an impact player’.
"Our job is to make sure he is prepared physically and mentally to start every game.
"Is he there yet? He is getting closer."
