Premier League sides Arsenal and Manchester United find themselves on the verge of both pulling off deals which can transform their 2013/14 seasons.
Arsenal are seeking to bag Argentine striker Gonzalo Higuain from Real Madrid, and smash their own transfer record in the process, replacing Robin van Persie and potentially kick-starting a whole new era.
A new dawn is already in effect at Old Trafford, with David Moyes poised to begin his six-year contract on July 1 (Monday).
One of the problems the Red Devils have faced in recent years is the lack of a world class central midfield player, the last players in the position they bought were Owen Hargreaves and Anderson in 2007, neither of who panned out as successes.
For Moyes to bag Thiago Alcantara, a player who Barcelona feel can replace Xavi should he stay, would be a major coup and get his management at Manchester United off to a terrific start.
On Wednesday both deals appeared to be nearing, with Barcelona claimed to have 'given up' on keeping Thiago, while Ancelotti's installation as Real Madrid boss was hoped to see him sanction the deal.
The '24 hour' period predicted by both The Guardian and The Independent that Ancelotti would give the deal the go-ahead in after his appointment has been and gone, and there may well be some nervous Arsenal fans worried that he will decide he wants to keep the Argentine.
Manchester United face a threat from Bayern Munich for the threat of Thiago, with his agent being Pep Guardiola's brother, and the newly installed Spanish boss is claimed to be willing to create space for him in a new formation by shifting Javi Martinez to centre-back.
Right now, fans of United and Arsenal are simply put - left hanging. Both clubs are waiting for choices to be made, with Real Madrid holding the cards in one case, and Thiago himself in charge of his own fate.
Both deals could yet come out and be sealed by time the weekend is out, but the longer the sagas are drawn out, the more chances there are for other clubs to hijack the deals and unscrupulous agents try to grab a slice of the action by offering them elsewhere.
If successful the wait will be worth it, if not it could be hearbreaking for both sets of fans.
