Why are Chelsea selling their two-time Player of the Year to reigning champions Manchester United? The Sunday Supplement panel will have answers following the Spaniard's big-money move to Old Trafford.
Martin Samuel (Daily Mail), Paul Hayward (Daily Telegraph) and Sam Wallace (The Independent) will join host Neil Ashton to discuss the headline-grabbing transfer and what it means for both clubs - as well as the Premier League title race.
In a week which saw United miss out on a Capital One Cup final at Wembley due to a penalty shoot-out defeat to Sunderland, our guests will consider whether David Moyes' move for Mata signals the start of a rebuilding process at the club or a desperate splash to save a stuttering season.
Also on the agenda this week will be:
TRANSFER TALK: Man United may be prepared to cough up £37m for Mata, but top-of-the-Premier-League Arsenal look set to stick with what they've got after Arsene Wenger ruled out the prospect of any new recruits arriving at the Emirates. Is that the right move, given Arsenal have free-scoring Man City and Jose Mourinho's Chelsea breathing down their necks in the title race? We'll discuss.
CITY SPRAWL: Man City, meanwhile, have been busy spending their money Down Under, where they've acquired A-League side Melbourne Heart, following their recent investment in the soon-to-be-formed New York City FC. What exactly are City trying to achieve with these purchases? Our pundits will shine a light on the matter - and also have their say on City's FA Cup contest with Watford, their recent Premier League title charge and former boss Roberto Mancini's claims their current success is down to him.
ANELKA ANALYSIS: This week Nicolas Anelka was charged by the FA for the 'quenelle' gesture he made against West Ham in December. Our panellists will share their views on the incident, the FA's response and Anelka's subsequent request for the charge to be dropped.
