Chelsea's talks with Palmeiras regarding a loan move for Andrey Santos have hit a speedbump with the two clubs disagreeing over the length of the deal.
The Blues'new £18m signing was denied a work permit for the Premier League, and will not be allowed to play for the club at the present time.
A temporary return to Brazil has been chosen as the solution with the player choosing Palmeiras due to their record of developing young players.
However, the Evening Standard report that there remains a final hurdle regarding the length of the loan with the Blues preferring to see him return for next season and Palmeiras insisting to have him until December.
