Back in June 2015, Chelsea made a "good" gesture by allowing legendary goalkeeper Petr Cech join our North London rivals Arsenal despite manager José Mourinho's wishes against it. But now that Arsenal could return the favour, they are keen in doing the exact opposite. According to the Daily Mail, the Gunners will do whatever they can to prevent Alexis Sánchez from joining any of their Premier League rivals, obviously including Chelsea.
To impede Chelsea and Manchester City, who have been the two major players in England in the chase for Sánchez, from succeeding in their mission, Arsenal are willing to sell the Chilean international to a foreign club despite having offered the player a new long-term deal for him to stay at the Emirates. This partly explains why Bayern Munich have taken the lead for his signature recently, with Italian giants Juventus also in the fold.
Not even Chelsea and City's supposed willingness to pay £45 million for a 28-year-old player with one year left on his contract has made Arsenal change their ways.
That said, even through our blue-tinted glasses, Arsenal’s strategy is completely understandable, considering how Sánchez managed to directly contribute to 34 of the 77 goals they scored this season in the Premier League. Losing such a player to a direct rival would be a most terrible move and while Arsenal do have a history of such terrible moves (Van Persie, Nasri, etc), maybe they are indeed turning a corner, much to our chagrin.
