Police are investigating reports that a threatening banner was left near the home of former Liverpool boss Rafael Benitez, who is set to join Everton.
Benitez’s arrival would be contentious as many Everton fans are opposed to the Spaniard, after he once described them as a “small club” in 2007.
He would be the first manager to lead the neighboring clubs since the 1890s.
A picture of the banner, which was posted online, read: “We know where you live. Don’t sign.”
A Merseyside Police statement said: “We can confirm police are investigating reports of a threatening banner at a location in Caldy today, Monday 28 June.
“At around 7am, it was reported that a banner made from bed sheets had been placed over a wall and bushes on a residential driveway, with wording which is thought to target football manager Rafa Benitez.”
CCTV and witness enquiries are being carried out in the area to trace whoever was responsible.
Benitez had a successful six-year spell with Liverpool where he won the 2005 Champions League and the 2006 FA Cup before reaching the Champions League final for a second time in 2007.
He later apologized for appearing to criticize Everton’s ambition after a Merseyside derby ended goalless in 2007.
