As Chelsea sealed the signing of highly-rated Brazilian attacking midfielder, Willian, from Anzhi Makhachkala, a shadow was cast upon the futures of the fellow playmakers Chelsea already possess.
Among them, quite unbelievably, the Blues' double Player of the Year award winner, Juan Mata, who is linked with a move away from Stamford Bridge.
Although Chelsea are known to be able to splash their owner's earnings in order to better their squad, the fact that Mourinho's side chalked out a whopping £30million surely shows a statement of intent during what was expected to be a relatively quiet transfer window for the west London outfit.
Willian had been heavily linked with a move to the Blues since the 25-year-old's former side; Shakhtar Donetsk met Chelsea in the Champions League.
The Brazilian produced a star-role in a confident display against the champions; bagging a brace in a tough away tie at Stamford Bridge.
At first sight it would seem Willian would be restricted to a less coveted role during his first year in blue, battling the likes of Eden Hazard, Kevin de Bruyne, Andre Schurrle, Juan Mata, and Oscar for a starting berth in the side vying to regain the Premier League title under their returning manager, Jose Mourinho.
It had circulated in the media that the ‘Special One’ demanded the right to negotiate transfer targets with current directer, Michael Emanalo, before the club lodged a bid to bring in a player that the manager may not have felt necessary. Therefore, this may be a completely Mourinho-fuelled acquisition.
Willian is a classy winger, who can also operate in the number 10 role. He is not known for his goalscoring abilities, but more for his killer passes and staggering amount of assists for team-mates.
Arguably not a solution to Chelsea's current striker crisis, the former Corinthians man has added to the qualities Mourinho's side already had.
While Willian may be seen as someone who has just provided depth, don't expect him to be a mere squad member; his move out of Shakhtar was almost solely triggered due to his ambition of forcing his way into Brazil's squad - with him having only achieved five caps to date.
The Brazilian selection staff had made it clear they will only devise their squad of players in the spotlight of football, ruling out players in the Ukrainian league.
In order for the big-haired new number 21 (the kit number in the picture of him undergoing his medical) to be selected for Brazil, he will demand to play every week, and with Mourinho seemingly a fan, we can all expect him to star regularly.
