Roberto Di Matteo has confirmed that Aston Villa are holding an investigation into the behaviour of Jack Grealish.

The Villa boss confirmed on Thursday morning that there was an ongoing process regarding the young midfielder.

Di Matteo gave an update, as quoted by Villa’s official Twitter account, after Grealish was caught up in another party storm that involved the police last weekend.

The Daily Mail report that officers were called to the Park Regis Hotel in Birmingham to kick out a group of 10-12 men and women in the early hours of Sunday morning.

In the report it is claimed the 21-year-old’s group upset fellow guests and that the party “featured balloons containing nitrous oxide, known as hippy crack”.

The substance is commonly known as hippy crack or laughing gas due to the relaxed feeling people who inhale it can sometimes feel.

Sunday’s incident is one of a long line of misdemeanours Grealish has been involved with in his short Villa career.

The England Under-21 international was caught up in a nitrous oxide scandal last year and in June 2015 the youngster was pictured drunk and sprawled out on a road while on holiday in Tenerife.

Several high-profile football stars have weighed in on the scandal with Stan Collymore, Dwight Yorke and owner Tony Xia all giving their verdicts.

Grealish has showed some encouraging form this season, scoring two goals, even though his side are place a lowly 18th in the Championship table.

Villa fans will now be hoping their starlet can put the antics behind him and focus on driving the Villans out of the Championship.

In other Aston Villa news, this midfielder has signed with the club after agreeing terms.
