James Rodriguez and Toni Kroos have arrived from Monaco and Bayern Munich, respectively, following highly impressive World Cup showings, and look set to become regulars in Carlo Ancelotti's starting XI once the Primera Division season gets underway.
Their arrivals, though, have let to intensifying reports that a number of Los Blancos' squad could be making way.
One man whose future has come under increasing doubt since the signing of Colombia's James is Isco, with the former Malaga man looking likely to be used as a substitute by Ancelotti given the wealth of attacking options the veteran coach has at his disposal.
|Isco's club at end of transfer window
|Odds from William Hill
Isco is 9/2 (5.50) with William Hill to join the Merseyside club before the end of September 1, while Manchester City have also been heavily linked with his signature, with the Premier League champions quoted at 11/4 (3.75) to sign the Spaniard.
Manchester United, meanwhile, are at 20/1 (21.00) with William Hill, though with Juan Mata and Ander Herrera impressing against LA Galaxy the Red Devils may look to cool their interest in attacking players while Arsenal's purchase of Alexis Sanchez should also rule them out of the running despite odds of 33/1 (34.00).
Despite huge interest in Isco, Real Madrid remain the favourites to keep hold of the starlet, with William Hill pricing him at 1/2 (1.50) to stay at the Santiago Bernabeu.
If the former Valencia trainee does remain in the Spanish capital, it could spell the end of Angel Di Maria's Real Madrid career, with the Argentina winger becoming one of the most talked-about individuals of the transfer window thus far.
Louis van Gaal's interest in bringing the 26-year-old to Old Trafford does seem to have cooled and that is reflected in the odds with Manchester United quoted at 16/1 (17.00) to join the 20-times English champions.
Instead, a transfer to Paris Saint-Germain looks to be moving ever closer, with the French outfit the favourites with William Hill to sign Di Maria at 1/2 (1.50) before the end of the window. Real Madrid, meanwhile, are at 6/4 (2.50) to keep hold of the Champions League final's man of the match.
Iker Casillas's future, meanwhile, remains up in the air following a poor World Cup coming off the back of a season spent largely on the bench with his club side.
Costa Rica goalkeeper Keylor Navas is close to a move to Madrid and, with Diego Lopez also providing competition for a starting berth, Spain custodian Casillas may be searching for pastures new this summer.
The 33-year-old is priced at 2/1 (3.00) with William Hill to join Arsenal as they continue to find a replacement for Lukasz Fabianski, with the same bookmakers quoting 4/11 (1.36) that he will not join Arsene Wenger's ranks.
