A third meeting with Nate Diaz or a lucrative super fight with boxing icon Floyd Mayweather Jnr are still possible options for Conor McGregor after UFC 205, according to his coach John Kavanagh.

McGregor will be looking to make UFC history when he takes on Eddie Alvarez at Madison Square Garden on Saturday 9 November as he aims to become the first man in the promotion's history to hold belts at two different weights at the same time.

Already featherweight champion having knocked Jose Aldo out in 13 seconds last December at UFC 194, the Dubliner will aim to add lightweight gold to his collection – but has also promised to deliver a huge announcement to the New York crowd before the night is over.

Speculation as to what that announcement might be has been rife throughout the build-up to the Alvarez fight, but the Dublin-born fighter has told fans not to listen to claims in the Irish press he is set to take an extended break from UFC.

Amid the fervent speculation over what is next for McGregor, his coach Kavanagh told the Elite Edge by Pundit Arena his immediate focus remains on Alvarez, but left the door open to some other tantalising prospects.

"There are so many options for Conor right now," Kavanagh said. "The Mayweather fight is still king of hanging in there. [Conor] is [145-pound/featherweight] champion. In a couple of weeks he will be the [155-pound/lightweight champion. The Nate trilogy is there. Maybe going back to [145lbs]. So a lot of things are up in the air. I am sure Conor will have an interesting announcement to make after the fight. So, stay tuned."

Both McGregor and Mayweather have fuelled talk of a boxing showdown between the two over the past 12 months. Mayweather, who retired with an undefeated professional record after stopping Andre Berto in September 2015, claimed in September the Dubliner had rejected the chance to fight him, while McGregor himself has insisted he will be happy to step into a boxing ring with the 39-year-old – if he is offered a fight purse of $100m.
