Sanchez is expected to answer questions from local media at the "Playing for a dream" tournament as speculation over his future continues, with Gunners boss Arsene Wenger revealing that he has had "positive" signs from the Chilean over recent text messages exchanged between the two.
But Wenger is steadfast in his hope that the 28 year-old will remain at Emirates Stadium.
"I have spoken through text and it was very positive", Wenger said.
Arsenal have offered Sanchez a new deal worth around £300,000-a-week and are hoping they can convince him to commit his long-term future to the club.
Asked if he felt Sanchez would stay, Wenger said: 'Of course.
"In England you also have to consider players like Alexis Sanchez played the whole season, finished the season really exhausted and went off to play in the Confederations Cup".
"Usually you need three weeks but they will have a programme that they have to follow and can be involved after one week to 10 days, they can be in the squad and play in part of games".
"It also depends on the shape they come back in".
Equally, Wenger believes that midfielder Jack Wilshere will stay at Arsenal after the England worldwide spent last season on loan at Bournemouth.
"Players like Alexis Sanchez played the whole season, finished the season really exhausted and went off to play in the Confederations Cup", said Wenger.
It was recently reported that Sanchez and his entourage had come to accept that Arsenal would not sell him this summer, with other rumours that they'd command as much as £80million for him if he were to leave.
