Arsenal boss Unai Emery has confirmed that Mesut Ozil will play a full part in the club's summer tour to Singapore.
Along with Carlos Bacca and Vicente Iborra, Vidal is one of a handful of former Sevilla players who have been linked with a return to Pablo Machin's side.
But Emery, speaking on Thursday, said: "For us Mesut is a very important player...today he is on holiday and I want him to relax good and I want, when he comes back with us, to start with a good mentality".
"We want to help to be well, fine with us". I want to work with him in a new way, and with an ambition for continuing with his quality [and] getting better in the team.
Emery and his coaching staff have been working at Arsenal's training base for the last two weeks, running the rule over those players not involved at the World Cup.
"I think last year was a hard year for all, not only for Mesut, [for] all the players, I want to give them confidence, to give them a chance every day in [training]". I think it is for the team.
Ozil is anticipated to be a member of the Arsenal's squad who are preparing to head to Singapore on July 22 for pre season games against both Paris Saint-Germain and Atletico Madrid. "They have the same holidays. He's coming with us to Singapore the first day", the Spaniard added.
"Yes, that's the plan and of course we try to do good pressing, but everyone knows what they have to do and that's important", he said.
Chambers played as a defensive midfielder in the second half of Arsenal's 8-0 win over Boreham Wood on Saturday after Emery made wholesale changes at half-time.
