Due to the big-money sale of David Luiz to Paris Saint-Germain for £50m and the Old Trafford exits of Rio Ferdinand and Nemanja Vidic, both Chelsea and Manchester United respectively will be searching for centre back reinforcements in the upcoming transfer window.
For former Liverpool, Newcastle United and Manchester United striker Michael Owen, it is imperative that, due to the dearth of quality defensive options, clubs who are in need of additions in this area "move fast".
Most big clubs in The Prem need to add defenders to their squads this summer. Not many top class ones about. Wise to move fast I'd say.— michael owen (@themichaelowen) May 28, 2014
Both Chelsea and United have already been linked with a standard of player who they would ideally like to purchase in order to maintain the elite-level standards their supporters have come to expect in the modern Premier League era.
For Jose Mourinho's Blues, a move for Real Madrid's utility Raphael Varane could be an option as reports in Spain state that the Portuguese has "his eye" on the Frenchman, a player Gunners boss Arsene Wenger was "obsessed by" earlier on in the season.
Borussia Dortmund stopper Mats Hummels, meanwhile, has been cited as Louis van Gaal's "priority" signing as United chief, while Feyenoord youngster Bruno Martins Indi is also suggested as a viable target.
"Moving fast" would no doubt appease any United fan disgruntlement as Red Devils supporters were left frustrated due to their transfer activity last summer, where Marouane Fellaini was panic-bought at the tail-end of the window, and will hope to avoid such a situation over the coming months.
