Madrid appointed Zidane on March 11, 2019, and he will manage the team till June 2022.
Real will return eventually, but for a notoriously demanding fan base and club hierarchy, that might be too long to wait.
However, injury problems have limited him to 79 La Liga starts in the past four seasons.
Rakitic scored five goals and created 10 assists for Barca last season, as Ernesto Valverde's side won another Spanish title and reached the Champions League semi-finals. This year some changes could help Real Madrid to stabilize and even win some silverware.
It is widely believed Madrid president Florentino Perez was the real reason the move collapsed. And James Rodriguez's change to Atletico Madrid was set up to deliver a much more rapid windfall with Diego Simeone's club probably to pay out all-around €45m (£41m) for the participant. "After speaking with the doctors, the best thing was for him to stay in Madrid".
Asked again if he would take action if it was proven Bale was playing golf instead of training, Zidane said: "We will see when we get back. And if I have to play golf, I will", he allegedly said.
The signing of Santini means Jiangsu would have to move out either Alex Teixeira or Eder Martins to accommodate Bale but, with both integral members of coach Cosmin Olaroiu's side, that looks unlikely.
"I think for me it could be a good time to have a new challenge somewhere else".
"I am not open to start a new chapter with no plan, with no clear idea, with not being transparent", he said.
A 7-3 hammering by Atletico Madrid in the USA was sandwiched between disappointing displays in defeats against Bayern Munich and Tottenham and a victory on penalties against Arsenal.
Bale, who has been in the Spanish capital since 2013, had been expected to join the CSL outfit on a three-year deal worth over US$1 million a week.
The France worldwide has been the subject of constant speculation during the summer and the former United striker believes the time could be right for him to move on.
Bale's aborted China transfer also suggests funds may not be available to bring in major Zidane target Paul Pogba in midfield.
Real Madrid is giving Bale the chance to decide his own future.
