It was not that long ago that Arsenal would try anything and everything to keep their biggest players but going into the summer transfer window, some inside the Emirates Stadium find themselves praying for someone to buy Alexis Sanchez.
The Chile international became Arsenal's second most expensive player in 2014, arriving from Barcelona in a £35million deal. His transfer to England has been widely recognised as a success with his first two campaigns, reaping 42 goals and a further 22 assists.
However, while the statistics – and his Instagram page – may suggest that all is well with Sanchez and the north London club, it appears as though there is growing discontent on both sides.

According to The Telegraph, Sanchez has been left frustrated with Arsenal's inability to win major silverware this season. They, of course, won the FA Cup in the previous campaign but have failed to effectively challenge for the Premier League in either of his two years at the club.
With his contract set to expire in 2018, Arsenal have been trying to tie Sanchez down to a new deal and his discontent will alarm officials in the Emirates boardroom. Indeed, if he refuses to sign an extension, they may have to cash in this summer to get full value for him in the transfer market.
But according to this latest report, the ill-feeling is a two-way street. Not only is Sanchez apparently unsettled but some Arsenal insiders are growing increasingly tired of the winger's attitude.
Mainly, they believe he is taking advantage of his star status by regularly turning up late for training sessions and continues to act selfishly on the football pitch.
It is no surprise that Sanchez's shoot-on-sight policy has irked his team-mates but this is the first we have heard of the 27-year-old not making it to Arsene Wenger's sessions on time.
Interest and replacement
Sanchez has already attracted interest from Europe's biggest clubs. Manchester City are believed to have placed him a shortlist along with Alex Oxlade-Chamberlain as Pep Guardiola looks to inject pace into his attack while Juventus are also interested.
Arsenal are apparently ready to sell if a sizeable offer comes in, especially if they can make a profit on their original outlay. However, Wenger would be reluctant to sell to a direct Premier League rival like City.
To replace him, the Gunners are trying to line up Borussia Dortmund’s Henrikh Mkhitaryan, who has been a stand-out star for Thomas Tuchel's side this season. While Marco Reus has the bigger reputation, Mkhitaryan has been going about his business in clinical fashion, scoring 19 goals and, rather incredibly, directly creating a further 24.
