The 28-year-earlier famous person spotted his country fail to qualify for Russia thanks in segment to a terrible error by the use of club-mate and Colombia goalkeeper David Ospina that gifted Peru a 1-1 draw.
Now Wenger has knowledgeable Sanchez he must put that melancholy in the back of him and get once more to his best for Arsenal without reference to problems over his long term.
The playmaker, out of contract in the summer season, has no longer scored in the Premier League this period of time after finding the internet 30 cases in club football in 2016-17.
His body language has been in a similar fashion unimpressive in the wake of a failed £60million summer season switch to Manchester City.
Wenger is just about certain to depart Sanchez out of his facet for the trip to Watford day after today amid problems over every his physically and mental state having most efficient returned from South America at 5pm the day prior to this evening.
“I believe to play at the top level, part of it is dealing with that kind of disappointment,” said the Arsenal manager.
“If you wish to have to make a big occupation it’s a little bit little bit of a roller-coaster, on account of you should have every now and then on a chief then three days later you’re on a low. It’s part of our process. Some deal upper than others with it.
“He is in a very difficult ideas. Chile merely gained the Copa America two instances, and now they don’t even transfer to the World Cup.
“Sanchez is 29 at the end of the 12 months, so the next one he’s going to be 33. He expected to transport. Certainly a big disappointment for him.
“I haven’t any doubt that he needs to perform. He under no circumstances is going on the football pitch to lose a football game, under no circumstances. Sanchez is a winner type.
“I watched the game with Brazil, what a physically game it used to be as soon as. He carried out in opposition to Dani Alves, that used to be as soon as a real combat, consider me. It’s worse to watch.
“You want your players to be in a positive ideas, and as smartly to have certain reviews. To transfer to the World Cup is the target of each single player who plays football.
“You have at all times to set objectives while you’re a soccer participant. When one is long gone, you focal point on one thing else.”
Wenger is conscious about Sanchez will have to react in short with the potential for a player lacking in motivation affecting all of the dressing room.
But he does sympathise with what the forward has been even though and has compared his situation to that of David Beckham, who become England’s talisman for a 10-year length around the turn of the century.
“You have in every generation a player who carries the pressure of expectation of a nation,” said the Frenchman.
“In France it used to be as soon as [Zinedine] Zidane. In England it used to be as soon as Beckham. We had other players in the staff, on the other hand it used to be as soon as Beckham. Why no longer Gerrard? I don’t know. But it used to be as soon as Beckham.
“In Chile it’s Sanchez. In Argentina after all it’s Messi. It seems like that there is any individual there in a national staff who has to carry the ability and absorb it and give protection to just a bit bit the rest of the staff.
“What does that do to that particular? It’s someone most often who likes it just a bit bit. They like to be on the front line.
“Overall what does it indicate? It way they’ve to care for the lows as smartly.
“Remember 1998 when Beckham has been sent off after Diego Simeone, he has been slaughtered proper right here, he’s no longer been picked for the principle two qualifiers after for the European qualifiers and he has been treated in this country like a person who has killed any individual.
“They need to take each the positives and the negatives.”
Despite this sort of primary error from Ospina, who palmed Paolo Guerrero’s indirect loose-kick into his non-public web, Wenger is adamant that gained’t affect on his goalkeeper’s relationship with Sanchez.
“I don’t think that will be a problem, but of course it happens sometimes, the coincidence of the competitions,” he said.
