The Times claim that no significant progress has been made in discussions with the star pair and that any deals are unlikely to have to wait until after the end of the transfer window.
‘Arsenal will start the Premier League season with doubts surrounding the long-term futures of Mesut Ozil and Alexis Sánchez after failing to agree new contracts with their two biggest stars over the summer,’ The Times report.
‘The club first began contract negotiations with both players’ representatives last September in the hope of tying them down to long-term deals, but no real progress has been made and the talks will not resume until after the transfer window closes at the end of the month.’
This is likely to be a defining saga of the season so you might as well get used to it.
