Tottenham Hotspur's best bit of summer business looks set to be their decision to sell Sandro to Queens Park Rangers for £8 million.
At the time the Brazilian departed, Spurs's decision was to allow him to leave was greeted with widespread frustration, but it looks to have been a masterstroke from Daniel Levy.
Sandro's quality is obvious and he would arguably be the most talented midfielder in Spurs's squad had he remained at the club, yet his fitness problems mean he is basically ineffective.
The 25-year-old has played just eight times since signing at Loftus Road and was ruled out until the new-year with a knee injury which he picked up in their last game against Newcastle United.
It is the latest in a series of injuries which he has suffered since 2012 and the fear is that Sandro's career will continue to be ruined by fitness struggles from now on.
As a result, receiving such a vast amount for a player who is rarely available appears to have been a great transfer dealing from Tottenham.
QPR must have been thinking they were getting a bargain when they brought in deal, but it seems like they may have seriously overpaid for the Brazil international.
Spurs's incoming additions during the summer have yet to make much of an impact, meaning that Sandro's sale looks the standout dealing which the club completed.
Mauricio Pochettino signed Michel Vorm, Eric Dier, Benjamin Stambouli, Federico Fazio and Ben Davies, but none have been entirely convincing in a Spurs shirt so far.
The hope will be that whatever funds are remaining from the Sandro transfer can be re-invested in January, where they will hope to buy a midfielder of similar ability to the Brazilian but without his fitness issues.
