The war of words between Rafael Benitez and Jose Mourinho has been hotting up ahead of Sunday's Community Shield clash at the Millennium Stadium.

Rafa and Jose in action.
Both teams have something to prove in the season's traditional curtain-raiser, and should field strong squads in a bid to claim bragging rights for the start of the Premiership next weekend.
Mourinho, while on Chelsea's tour of the US recently, fired the first shots of what is expected to be another season of baiting aimed at Anfield.
The Chelsea boss, claiming Arsenal and Manchester United have bought better in the summer and worried him more than Liverpool, again branded the Reds as defensive and boring.
Benitez however, was quick to distance himself from the potential slanging match, saying: `You should all know me by now, I do not comment on other managers but concentrate on my own team. I prefer not to waste my time with such things.
'I promise you I am not concerning myself too much about what Chelsea are doing.'
Both teams have strengthened their squads over the summer, and will give their new signings their first taste of Premiership opposition on Sunday.
Chelsea have spent nearly £50 million bringing Andriy Shevchenko, John Obi Mikel and Michael Ballack to the club, while they're also in negotiations to bring in Arsenal leftback Ashley Cole in one of the most drawn-out transfer saga's of the summer.
Liverpool have also spent big, capturing Jermaine Pennant, Craig Bellamy, Fabio Aurelio and Gabriel Palleta for nearly £20 million. While also trying to lure Dirk Kuyt from Feyenoord in a reported £10 million deal.
Neither team have enjoyed a successful pre-season campaign, tasting defeat and failing to impress against weaker opposition.
Of the two, Liverpool will be more prepared after their 2-1 Champions League qualifier victory against Maccabi Haifa on Wednesday. While Chelsea are still struggling for fitness, with the likes of William Gallas still yet to make an appearance in pre-season.
Liverpool have proved to be Chelsea's bogey team in recent contests and Benitez remains confident of success in the tactical battle against Mourinho.
Often able to frustrate the Portuguese tactician, Benitez has ground out wins in the FA Cup and Champion's League in recent seasons, although Mourinho had the edge in the last Premiership campaign, beating the Reds 4-1 at Anfield and 2-0 at Stamford Bridge.
Both sides will be keen to avoid the scoreless affairs that dogged their Champion's League campaign's last term, although Liverpool are expected to play the same stifling 4-5-1 formation with a lone striker and two wingers that has been so successful in the past.
Chelsea however, have already shown their intention for the season by scrapping the 4-5-1 in favour of an attacking 4-4-2. Without Makelele on Sunday, given extra time to recover from the World Cup, Mourihno has a chance to see the formation in action against a tougher opposition.
The season-opener is traditionally a cagey contest and there might prove to be more action on the touchline if Benitez and Mourinho get involved. Both managers will be keen to get one-up on the other before the real action kicks off next week.
• Soccernet highlights some of the key battles to look out for on Sunday:
ANDRIY SHEVCHENKO vs. JAMIE CARRAGHER
Shevchenko arrived from AC Milan in a deal worth around £30 million after establishing himself as one of the finest strikers in the world. He turns 30 this season and is under a little pressure to prove he is worth such a huge fee, but the truly word-class Ukrainian is also tipped to set the Premiership alight with his potent finishing and blistering speed.
Carragher has become the cornerstone of Liverpool's defence after making the transition from utility-man to centre back. Unlucky not to feature more for England at the World Cup, Carragher helped his side to numerous clean sheets last season with his excellent positioning and pace. He will have to be at his very best to keep Shevchenko quiet though.
MICHAEL BALLACK vs. STEVEN GERRARD
Ballack is another high-profile arrival at Stamford Bridge, joining the club on a free transfer after a successful spell at Bayern Munich. He is also approaching 30 but his performances at the World Cup with Germany suggests he remains influential. If he can form an understanding with the like-minded Lampard in midfield, Chelsea could reap the rewards.
Gerrard has led Liverpool superbly in recent seasons, dragging them back into the Champions League final in 2005 when they were 3-0 down at half-time against Milan. Also rescuing his side in the FA Cup final against West Ham with a late strike, the skipper is invaluable to the club and will look to hurt the side he almost joined last season with his penetrating runs and vicious shots.
JOHN TERRY vs. CRAIG BELLAMY
Leading from the back with his organisation and tough tackling, John Terry is the first name on the teamsheet for Chelsea and has now been given the England captain's armband too. Has been criticised for a lack of pace that Bellamy could exploit, but still a rock in defence that Liverpool will find hard to crack.
Bellamy has often caused controversy with his discipline off the field, but he has proved to be a match-winner when playing. His pace can trouble any defence and he has the potential to form a good 'little and large' partnership up front with Peter Crouch. Will pounce on any chances, as he showed against Maccabi Haifa.
Probable line-ups:
Chelsea: Cudicini, Ferreira, Terry, Carvalho, Bridge, Ballack, Lampard, Robben, Wright-Phillips, Shevchenko, Drogba.
Liverpool: Reina, Riise, Carragher, Hyypia, Finnan, Alonso, Gerrard, Sissoko, Pennant, Zenden, Bellamy
