Liverpool is investigating an alleged incident involving Wolves defender Jonny Castro Otto and a ball boy during Sunday's clash at Anfield.

The Spanish wing-back is reported to have made contact with the youngster when attempting to retrieve the ball during Wolves' contentious 1-0 Premier League defeat.

A short statement from the Reds said a probe has been launched.

"The club is aware of the incident and will follow established protocols in terms of gathering the relevant information," the statement read.

"While that process takes place we will be making no further comment."

Liverpool maintained its unbeaten record in the Premier League this season in a VAR-controversy filled fixture.
