Arsenal officials are concerned with the lack of movement in contract negotiations with Mesut Ozil but remain confident a deal will eventually be agreed.
Ozil is currently one of the highest earners at the Emirates with his current deal believed to be worth around £140,000-a-week. After a stellar season, Arsenal are ready to make him their first ever £200,000-a-week player. The deal is believed to be made up of a basic wage with a number of bonus clauses based on team and individual success.
According to The Mirror, negotiations between the Gunners and Ozil's representatives have been dragging on for many months even though an agreement has been reached in principle.
With two years remaining on his current contract, there is no immediate rush to push the negotiations through and Ozil himself will now be fully focussed on Germany's Euro 2016 campaign.
That means Arsenal fans could be forced to wait until late July to seal the playmaker's future. Although there is a slight concern that Ozil could backtrack on the verbal agreement, there is every expectation that he will make good on his promise and commit to continuing under Arsene Wenger.
But there is even more concern with Alexis Sanchez, who himself has been in talks with Arsenal over a contract extension for many weeks. Also on around £140,000-a-week, the Chilean has been offered a significant pay rise to place him just behind Ozil in the pay scale.
However, Sanchez has grown discontent with life at the Emirates after a frustrating campaign for both himself and the Gunners. With Bayern Munich and Juventus interested, it seems Sanchez might be considering whether his career will be better served with a bigger club on the continent.
Juventus and Bayern Munich have dominated domestically in recent years, both winning four titles in a row while Arsenal haven't topped the Premier League since 2004.
Arsenal remain keen to keep him on board but could be tempted to cash in if a club offers them the chance to make a significant profit on the £35m they originally invested. Sanchez's current contract expires in 2018.
There will also be crunch talks with a number of Arsenal's British core. Jack Wilshere is expected to be offered a new contract while Alex Oxlade-Chamberlain and Theo Walcott will both seek reassurances over their place in the team.
Both wingers struggled to break into the team last season and the emergence of Alex Iwobi only sent them further down the pecking order. Reports would have us believe that Arsenal are open to selling Walcott and/or Oxlade-Chamberlain for the right price.
Kieran Gibbs and Carl Jenkinson are also expected to leave in the summer transfer window after falling out of favour.
