The 30 year-old has stepped into the breach to tackle ‘Maravilla’ after preferred opponent Julio Cesar Chavez Jr. failed a doping test and Murray is intent on ending any hopes of a rematch between the two when he battles Martinez next month.
“Everything’s going really well. Still a few weeks to go yet but everything’s on track and things are starting to come together,” Murray told World Boxing News.
“I’m buzzing that the fight is just a few weeks away. I’m getting more confident the closer it gets and I can’t wait to get over there and shock the world.”
Some are predicting an uphill struggle for Murray based on the stature of Martinez in the pound for pound rankings, although the southpaw recently turned 38 and could be ripe for an upset if the St Helens man gets his tactics right on the night.
“Regardless of his age, I know I’ve got the style to beat him. Martinez is a great fighter but I’m better and I’ll prove this when we fight,” said Murray.
Manager Marsh is equally as confident as his fighter after witnessing Murray’s early gym work and has meticulously planned the pre-bout preparations for the clash, which takes place Velez Sarsfield’s football ground in Buenos Aires.
“Everything has been normal so far,” explained Marsh. “Martin is one very dedicated boxer and he gives his best all the time.
“The only thing different for this fight is his tactics, which his coach Oliver (Harrison) won’t leave any stone unturned in arranging.
“We are planning on going to Argentina twelve days before the fight as there is only three hours time difference, as there isn’t a problem with altitude or temperature.
“We had to find a fine balance for Martin with having a wife and two kids and one due any day and this is what Martin is happy with as it also allows us too finish off training in the UK.
“The majority of training will be complete for when we get there,” he went on. “They are appointing us a gym, but if the hotel we are staying has got suitable training facilities, we may use that as the gym is not adequate, which we inspected on our press conference in Argentina
“This fight for Martin is massive. Even when we were in Argentina with Ricky Hatton he couldn’t believe how big it was. It hasn’t caught the press over here, but maybe they think ‘oh it’s just a Brit going too lose.’
“I don’t know why but the amount of requests from Argentina and the US for Martin is unbelievable. I’m no good on computers, but this last couple of months it seems all I’ve done is sit at a computer!”
Marsh then finished by commenting on the fact that 10,000 tickets were sold for the clash in just 24 hours, by adding: “Ticket sales are as expected for any homecoming for a local hero. They know this will be a remarkable event.”
