Sanchez is not the only Arsenal player that is in the a year ago of their contracts, with Mesut Ozil and Alex Oxlade-Chamberlain's contracts also expiring in June 2018, and it will be interesting to see how Arsenal deal with these situations.
Mertesacker's replacement, new Bosnian defender Sead Kolasinac, impressed Arsenal's fans with a series of shuddering challenges before cancelling out Victor Moses' opener with a headed 81st-minute equaliser.
Wenger though stressed on the fact that Sanchez remained "focused" on playing for Arsenal this season.
Ahead of his side's Community Shield penalty shoot out victory over Chelsea, though Sanchez sustained the knock and will now absent for the games against Leicester and Stoke City. In a transfer window where most clubs spent on multiple star signings, Arsenal were content getting in French striker Alexander Lacazette for a club record fee of €53 million. There are encouraging signs from his early performances, but he'll need to be even better when the Premier League starts. They have got the money to spend. Therefore it is surprising that there haven't been any major links with a central midfielder this summer.
If Sanchez departs in the coming weeks, it's likely he's already played his final game for the club because of his injury.

The US Secretary of State Rex Tillerson is also at the forum, where he spoke about North Korea. Some experts believe the USA mainland is now in range of a North Korean military strike.
The Gunners boss replied: "I had an impact on the season, because at some stage the players came to see me and said:,'What's going on boss?" After all, the club had just won the pre-season double, lifting the coveted Emirates Cup and Community Shield trophies.
"It's exciting. The Premier League is back".
The reigning champions are also shorter than ever at 5/2 to finish outside of the top four this season.
Arsenal could have up to 11 first team players unavailable on Friday.
It will be interesting to see what approach Wenger takes towards the Europa League.
Makwala proves his fitness and makes 200m semi final
We only had benefit from the media relating to Makwala's not being allowed to compete which left us heart-broken. There was a second world title for the Czech Republic's women's javelin world record holder Barbora Spotakova .
The striker managed 16 goals and seven assists in all competitions previous year despite not making a start until Boxing Day, so he's more than worthy of being a back-up to Lacazette.
"It is going to be different this year".
Nonetheless, football specialist, management specialist or not, we're inclined to disagree with Wenger on this one.
Chelsea have 13 or 14 very good players who will match anyone.
