Grealish is set to become an uncle after his sister announced her pregnancy

Manchester City star Jack Grealish is set to become an uncle this summer after his younger sister announced she is pregnant.

Kiera Grealish, 22, is set to give birth to her first child with boyfriend Josh Murphy in August having announced the news on social media.

It comes a week after they celebrated their four-year anniversary. The couple wrote on Instagram: 'Baby murphy... a dream come true, half of me and half of you.'

As well as Kiera, Jack is also close to his other sister, Hollie, who was born with cerebral palsy.

Holly commented on the announcement post she 'can't wait' to meet her niece or nephew later this year.

The expectant father, Josh, is a model who is signed with Manchester modelling agency Nemesis.

In their Instagram post, the couple showed photos of their first baby scan, a pregnancy test, baby booties, as well as a photo of Josh kissing Kiera's bump.

Jack's long-time girlfriend, Sasha Attwood, also sent her well wishes alongside a number of other wives and girlfriends of other football players.

On the pitch, it has been far from smooth sailing for Jack recently after suffering a groin injury in Manchester City's midweek Champions League win over Copenhagen.

The 28-year-old limped off during the first half at the Parken Stadium, despite trying his best to stay on the pitch before eventually conceding he couldn't carry on.

It was clear that the England international was suffering with a muscular injury and a timeframe of two to three weeks has been attributed for his recovery, as reported by The Telegraph.
