General view of Ibrox - Rangers
Caixinha has won titles before in Mexico with unfancied side Santos Laguna, and the Portuguese boss may want to consider looking back at his former team for recruitment.
One stand out name is former Chelsea whizkid Ulises Davila, who signed permanently with the club in 2016.
Davila joined Chelsea from Guadalajara in 2011 after making a name for himself as a Mexican youth international and even earning a senior call-up.
As with many youngsters who have joined the Blues, his career stalled with a series of loan spells.
The attacking midfielder have five loans in total, playing in Holland, Spain, and Portugal, before deciding to cut his losses on breaking through at Chelsea and returning to Mexico last year.
At Santos Laguna he has benefitted from stability, becoming a regular and getting on the scoresheet.
He told ESPN last year: "Mexican footballers have a tough time winning trust; it's difficult to get opportunities. The opportunities are very few, so you have to give your all in every single one of them."
If there is one manager who will believe in the 25-year-old then it is Caixinha, who spent time managing in Mexico and has a clear eye for talent.
Davila's preferred position is as a number 10 but he is able to play on either wing, and could be a valuable asset for Rangers if they choose to make a move.
One fair criticism of Rangers this season is that they have not got enough flair in their side, players to make fans get off the edge of their seats.
Davila can help address that, with a desire to run with the ball and shoot from outside the box, he could become an exciting signing if he can finally realise his outstanding potential.
