Ferguson is reported to have aimed another dig at his former Liverpool rival during an interview in Italy, claiming he is not friends with Benitez.
Benitez, who left Liverpool in the summer of 2010, has had a long-running feud with Ferguson since his time at Anfield and the Spaniard insists he is not bothered by the latest barb.
Haha
"If the big rival of Liverpool Football Club is just thinking about me months after [leaving] that is quite positive. It means we were doing something well."
