If Manchester United's pursuit of Juan Mata, a player they are reportedly imminently close to signing pending a successful medical examination later today, Friday, can be regarded to be opportunistic, then the transfer coup that Chelsea manager Jose Mourinho may well have up his sleeve is downright audacious.
Mata, depending on whether one sides with a BBC report or Sky Sports, is about to join David Moyes' attempted revolution at Old Trafford for a fee of either £35m or £40m, respectively. This, after the Blues already pocketed an estimated £17.5m for fringe winger Kevin de Bruyne.
Former Benfica midfield battler Nemanja Matic has already been purchased and, if a report in El Mundo Deportivo is to be believed, then the Serbian may well be joined by a further two recruits as Mourinho is allegedly aiming to pull off an extraordinary - and unprecedented - FOUR player swap deal involving two Blues, Atletico Madrid, their full back and their star striker.
The players on Mourinho's radar include Filipe Luis, a 28-year-old defender, who has been a mainstay in the Atleti line-up, featuring 18 times in the Primera Division and four times in the Champions League. He is valued at £12.5m by transfermarkt.co.uk, commits a tackle every 21 minutes, has a passing accuracy of 81% and has provided 20 key chances for his team.
Further up the field, Mourinho also reportedly wants Luis' Atletico pal Diego Costa (who Here Is The City argued would be a far greater fit for Mourinho than Wayne Rooney here), a prolific goal-scorer capable of returning a goal or an assist every 80 minutes of league football in Spain.
Heading the other way, El Mundo Deportivo explain, would be a player Atleti already possess and one they publicly admire - goalkeeper Thibaut Courtois, who is thriving in a three-year loan spell at Vicente Calderon and could make his move permanent, along with another Chelsea loan star Romelu Lukaku, a tank of a striker over half of the way through a temporary stay with Everton.
