Four clubs are said to be keen on the ex-Rangers boss, who left Ibrox on Thursday.
The agent of sacked Rangers boss Pedro Caixinha claims the Ibrox side are holding up his move to a new club.
Speaking to the Daily Record, Nuno Batista says teams in Mexico have already approached his client, who was dismissed by Rangers last week.
But Batista adds that talks are still ongoing with Rangers over Caixinha's severance package, with the Portuguese coach still having more than two and a half years left on his Ibrox deal at the time of his exit.
"Yes, there has been contact from Mexican clubs, but we cannot talk to anyone until we reach agreement with Rangers," Caixinha's representative says, as quoted by the Daily Record. "We are still trying to finalise the details with them and that is our priority for now.
"After that, we can analyse the offers that have come in both from clubs in Europe and elsewhere. We are not ruling anything out for now.
"Pedro has a great affection for Mexican football. He obviously worked there for a few years and did very well. He loves to work and get involved with a serious project and there are plenty of opportunities in Mexican football."
The Daily Record lists Caixinha's old side Santos Laguna, as well as Guadalajara, Cruz Azul and Pumas, as being interested in the 46-year-old.
Caixinha led Santos, who became a partner club of Rangers' Old Firm rivals Celtic in 2011, to the Liga MX title two years ago, before a move to Qatari football with Al-Gharafa.
He headed to Ibrox as Mark Warburton's successor in March, but left Rangers fourth in the Premiership standings, despite a heavy summer recruitment drive which saw 11 players added to last season's third-placed team - at a cost of almost £9 million.
