Middleweight contender Chris Eubank Jr. recently spent some time training with former two-time unified heavyweight champion Anthony Joshua.
Eubank is preparing for his upcoming February 5th grudge match with Liam Williams.
Joshua is hoping to bounce back after suffering a twelve round decision loss to Oleksandr Usyk in September of last year.
The British superstar has exercised an immediate rematch clause,
There is no word on when or where the rematch will take place - but some are expecting a date in April or May.
Joshua, who trained for his entire career with Robert McCracken, has been exploring the possibility of hiring a new trainer and he's been spotted with several high-profile coaches in the United States and other countries.
During their time together, Eubank liked what he saw from Joshua - and he advised him to choose carefully when it comes to a new coach.
"Importantly, he was looking hungry," Eubank said about Joshua to Sky Sports.
"Despite how much money he has made and how many fights he has won, the hunger is still there which means a lot. He is trying to get better by looking for a new trainer so he can change his tactics and beat Usyk. I would love to see that.
"He showed in his second fight with Andy Ruiz Jr that he can switch game-plans and learn from his mistakes. After a loss, you think: 'How can I get better? How can I do things differently?' You can't keep doing the same thing because it didn't work.
"You have to find somebody that you really connect with. Don't go to the first person that you meet. Go to America, go to other countries. If you hear someone is good to work with? Go and work with them. Test it out. Then choose."
