The 19-year-old, whose twin brother Nathan is also in the City reserves, is the latest Academy player to catch the eye as City's second string have gone top-of-the-table.
Jonathan has played 8 of 9 league games, of which City have won seven and lost just 2, and scored his first goal in the 2-1 win over Manchester United last week, before adding his second as City beat West Brom 3-1 this week.
"When you see their performances in the reserves from players like Jonathan D'Laryea you realise they are not far away," first-team coach Derek Fazackerley told the official City website.
"He plays in central midfield and is certainly an athletic player and can get up and down from box to box.
"He is very strong and of late is starting to score one or two goals in the reserves as well.
"It is good for the club and good to see young players like Jonathan starting to establish themselves and starting to train with the senior players.
"He's trained with us several times and he has not looked out of place. Certainly in the last 4 or 5 weeks he has been outstanding in the reserves."
