Manchester City winger Jack Grealish was burgled while the England star was playing in his club's Premier League match at Everton on Wednesday.

Grealish's Cheshire mansion in north-west England was targeted by thieves as he was in action for the Premier League champions during their 3-1 victory on Merseyside.

Members of Grealish's family and his fiancee Sasha Atwood were watching the televised match at the house when they heard a disturbance, according to reports on Friday.

An alarm was raised and an emergency response was launched with a helicopter, police dogs and a number of officers sent to the property, but no suspects were detected.

It was reported the robbers made off with £1 million (HK$9.94 million) worth of jewellery and watches.

Grealish, 28, was informed of the raid after City's match finished.

A spokeswoman for Cheshire Constabulary said no arrests had been made at this time and enquiries were continuing. (AFP)
