The Irish bond was once again on display as Conor McGregor took to social media to send his regards to fellow-Irishman Katie Taylor.
The showdown inside MSG will determine the undisputed lightweight champion as Serrano jumps from featherweight to take on Taylor in an attempt to get her hands on the undisputed gold.
There's no denying the power on Serrano's hands. It will be interesting to see who gets her hand raised this weekend after everything is said and done.
