(CNN)When it comes to spats with managerial rivals, Manchester United manager Jose Mourinho is arguably very much in a league of his own.

He infamously labeled Arsenal manager Arsene Wenger "a voyeur" when he was Chelsea manager and has exchanged a series of barbs with former Liverpool, Real Madrid and Inter Milan boss Rafael Benitez -- and the Spaniard's wife.
Not forgetting Mourinho's run-ins with Barcelona, Manchester City and the Chelsea first team during the 2015-16 season, saying he felt "betrayed" by his players.
But his recent verbal jousting with Chelsea manager Antonio Conte really has taken things to a whole new level.
Conte has labeled his Portuguese rival a "little man" and a "fake," while Mourinho aimed low by bringing up the match-fixing case in which the Italian was exonerated after an investigation. Ouch.
"Either way it's not befitting as a manager of Manchester United," tweeted Andy Hilton. "It seems to be a smoke screen for stale tactics."
We take a look at the timeline of their feud here. And whatever you do keep February 25 free in your diary.
That's when United face Chelsea at Old Trafford in the English Premier League. The traditional post-match handshake between managers could be compelling viewing.

      "Minimum gold, maximum gold'

      Talking of women, Ryoko Tani is widely considered to be the best female judoka of all time, but the Japanese great's career was also marked by a refusal to allow gender to prevent her fulfilling her sporting ambitions.
      As a young girl, Tani had to overcome the resistance of her mother, who would have preferred her to take lessons in something "more fitting" such as tennis or the piano.
      The Japanese hotshot had a motto -- "minimum gold, maximum gold" -- which sums up Tani's competitive streak. You can read more about this remarkable athlete here.
