With Mario Mandzukic apparently unhappy at Atletico Madrid, Tottenham Hotspur have been handed an opportunity that they simply cannot refuse.
It has been widely reported that the powerful Croatian forward has become disillusioned with life at the Estadio Calderon after Atleti opted to bring in Fernando Torres and he is already looking for a move away.
Torres was given a hero's welcome when he returned to the club he started his career at, but their fans haven't taken to Mandzukic in the same way.
Atletico's supporters have been treated to watching some of the most gifted strikers in European football in recent times with the likes of Sergio Aguero, Diego Costa and Falcao all plying their trade for the La Liga champions, but Mandzukic hasn't been able to earn the same kind of plaudits.
Although the former Bayern Munich man still has 14 goals to his name this season, from 27 appearances, his differing style to his predecessors means that he has struggled to win over the fan-base.
It was expected that Mandzukic's stay at Atletico would be a lengthy one, but Spurs must capitalise on the uncertainty over his future and make him their main target this January window.
The Lilywhites are said to have £35 million to spend, before any of their sales have even taken place, and they should plough most of these funds into signing the 28-year-old.
Mandzukic is a forward of great ability and, although they wouldn't be able to offer him Champions League football, their lofty position in the Premier League table combined with their good form should make them an attractive proposition.
Spurs should have no problems paying his wages, either, as they intend on offloading some of their high earners.
The expected sales of Paulinho, Roberto Soldado and Emmanuel Adebayor will lessen their wage-bill hugely and provide Spurs with the funds to bring in a genuinely world-class player.
That is the criteria that Mandzukic fits in and although he would unlikely to have been considered a realistic target until recently, Spurs must act fast to bring him to White Hart Lane.
If they are able to he could be the difference between a Champions League place or another season of Europa League football and the expensive initial outlay would, therefore, be paid for within just six months.
