Where Should Jose Mourinho Spend Reported £50M David Luiz Transfer Fee?
David Luiz will join Paris Saint-Germain this summer, leaving Chelsea after three-and-a-half years in west London.
Confirmation of the Brazilian's transfer to the Ligue 1 champions was broken on Chelsea's official website on Friday.
The exact fee is still unknown, although Sam Wallace's report in The Independent suggests it will be close to £50 million, breaking the world record transfer for a defender.
It's a significant figure—one that doubles the £24 million Chelsea paid for Luiz in January 2011—and outlines Chelsea's intent to comply with UEFA's Financial Fair Play regulations that have recently seen PSG and Manchester City suffer heavy fines.
Luiz's transfer now gives Chelsea significant funds to strengthen their squad over the summer, but how best should Jose Mourinho spend the money?
Bleacher Report identifies some areas where the Blues can invest.
Give Gary Cahill a Pay Rise
As one half of Chelsea's first-choice centre-back pairing, Gary Cahill has become essential to the Blues since his January 2012 move from Bolton Wanderers.
The Englishman was awarded handsomely when joining Chelsea, being given an £80,000-a-week contract, as reported by Ralph Ellis in the Daily Mail.
It's now time Cahill is given parity with Chelsea's other stars, with a wage rise to not only outline his achievements, but also to show he is valued just as much as the club's other top earners.
Cahill has developed into an exceptional talent, and with Luiz's transfer removing one high earner from the wage bill, it means there is room to give Cahill a salary befitting his position.
Sign Luke Shaw
It was expected Luke Shaw would join Manchester United this summer, but The Guardian's Jamie Jackson has reported that a potential move to Old Trafford has hit a snag, leaving the Southampton defender to consider his options.
Patrice Evra has also signed a one-year extension to remain with the Red Devils for 2014-15, adding further doubt as to whether Shaw will be joining the club.
With a potential £50 million windfall from David Luiz's transfer to Paris Saint-Germain, Jose Mourinho now has more than enough financial backing to chase Shaw without worrying too much about Financial Fair Play.
At just 18, the Southampton left-back has a long career ahead of him, and with Ashley Cole's contract expiring in just a few weeks, a move for Shaw will give the Blues a rising star in a position they need to fill.
Bolster the Forward Ranks
Now David Luiz has all but joined Paris Saint-Germain, it means the rumored swap deal involving Bayern Munich's Mario Mandzukic is definitely off.
The Metro had reported that Bayern were interested in the Brazilian defender, using their striker as a makeweight in any potential deal.
With Diego Costa expected to join this summer, per Sky Sports, Chelsea still need to add more quality up front.
Samuel Eto'o's contract expires shortly, while Fernando Torres and Demba Ba have struggled in front of goal.
If Chelsea want to win the Premier League title and other trophies next term, they are going to need more than Diego Costa to help them do it.
Mandzukic is an option, but there are other world-class strikers Chelsea could potentially snatch with a £50 million transfer kitty.
PSG's very own Edinson Cavani could be an option after a mixed debut season in France, while Monaco's Falcao may also be tempted.
Both would command significant fees, but Chelsea now have the capabilities within Financial Fair Play regulations.
Sign Yaya Toure
Imagine a midfield pivot of Nemanja Matic and Yaya Toure.
The physical attributes of both players is enough to whet the appetite, and with them pairing together in the Chelsea midfield, it's difficult to imagine many teams combating that combination.
This week has seen Toure's Manchester City future come under question after the club, in his view, failed to properly acknowledge his birthday, per Sky Sports.
With that in mind and with David Luiz's transfer fee behind them, Chelsea should look to capitalize.
City have also been reprimanded by UEFA recently for their failure to comply with Financial Fair Play regulations, so a big bid from Chelsea could very well force their hand as the club looks to make amends.
They may have recently been crowned Premier League champions, but City are vulnerable right now, and Chelsea should look to make the most of that.
