Jose Mourinho has told Rafa Benitez's wife to "take care of her husband's diet" in response to claims she made about the Chelsea manager leaving "mess" at various clubs.
Montserrat Seara, the wife of Benitez, joked with a Spanish newspaper that her husband was at Real Madrid "tidying up" the "mess" left behind by Jose Mourinho.
Speaking to La Region, Seara said: "We tidy up his messes. If you think about it, of course you end up crossing paths. There are only a few world-class clubs out there."
However it seems that Mourinho has failed to see the funny side of her comments. Speaking after Chelsea's 4-2 penalty shootout win over Barcelona in Washington, the Portuguese had this to say: "The lady is a bit confused. Her husband went to Chelsea to replace Roberto Di Matteo and he went to Real Madrid and replaced Carlo Ancelotti.
"The only club where her husband replaced me was at Inter Milan, where in six months he destroyed the best team in Europe at the time.
"If she takes care of her husband's diet, she will not have any time to talk about me."
During their spells a decade ago as manager of Chelsea and Liverpool respectively, Mourinho and Benitez often clashed both on the touchline and in the media. And their feud was reignited when Mourinho left Inter Milan in 2010 to join Real Madrid having completed the treble.
Benitez replaced Mourinho at the San Siro and announced: "There’s the coaches, first Mancini, then Mourinho and now me, and I hope to win more than them. We could win six trophies this season.”
To which Mourinho replied: "Another thing is also true that should he lift the Intercontinental Cup, he will have only won two games compared to my 13. Therefore it will be my trophy and not his."
Benitez has also managed Chelsea during his career on an interim basis and despite winning the Europa League in 2013, he left at the end of the season and was replaced by Mourinho who returned for a second spell in charge.
Chelsea won their final pre-season fixture in North America against Barcelona in the early hours of this morning. A 2-2 draw at the end of 90 minutes meant a penalty shootout with Chelsea emerging victorious 4-2. Eden Hazard and Gary Cahill scored in normal time for Mourinho's side.
The Blues play Arsenal in this Sunday's Community Shield at Wembley before a final pre-season fixture at Stamford Bridge against Fiorentina on August 5.
They kick off their defence of the Premier League title on Saturday August 8 at home to Swansea City.
