Even with his circumstances changing in recent days, Fernandez still describes his side's chances of signing the Arsenal forward as "remote".
Alexandre Lacazette will wear the number nine shirt for Arsenal this season, the club confirmed on Tuesday.
Arsenal risk losing Sanchez for free next summer if he does not sign a new deal.
"One is to win trophies but more importantly it is to know who we are, and what is important to us in the game".
Their shortlist of right-back targets includes Monaco's Djibril Sidibe, Benfica's Nelson Semedo, Valencia's Joao Cancelo, Real Sociedad's Alvaro Odriozola and Bayern Munich's Joshua Kimmich.
A man who spent three years working with Lacazette between 2011 and 2014 told France Football: "Olivier and Alexandre are two different players that Arsene needs". Arsene Wenger will be subjected to incredible levels of criticism having signed a two-year contract extension despite last year's disappointing finish while Jose will also have to oversee a massive improvement domestically after another summer of big spending.
Asked if he remained determined to keep Sanchez and not let him go to a Premier League rival, Wenger replied: "Yes, that is a continuation of what I said at the end of the season".
Defenders Hector Bellerin, Calum Chambers and Rob Holding, who were involved in the under-21 European Championship, will not travel either.
The matches go toward no competitive trophy; the club is just looking to spread its brand as the players get up to match-fitness on the other side of the globe.
Lukaku is set to be announced as a United player this week ahead of a training camp at UCLA in California. "Im sure hes happy to be here and to be able to play with us, and were pleased to be able to assist him and help him to score as many goals as possible".
Wenger continued: "I've stayed here for a long time because of the values I hold close to me".
