He is now 4-1 in his last five fights and looks set for a massive year in 2023. Still just 26, Tsarukyan has shown tremendous championship potential so far.In contrast, Michael Chandler is 2-3 in his last five UFC fights. Although he has delivered some electrifying performances, the American's championship aspirations have suffered due to his all-action style of fighting.

The idea of the duo coaching the next season of The Ultimate Fighter has also been floated around.MMA Orbit@mma_orbitConor McGregor vs. Michael Chandler on TUF would be one of the best seasons ever!#UFC #MMA87344Conor McGregor vs. Michael Chandler on TUF would be one of the best seasons ever!😍#UFC #MMA https://t.co/gqp88EDYYAWhen Michael Chandler stated that he would beat Islam MakhachevAlthough Michael Chandler has accrued more losses than wins in the UFC, the former NCAA Division I All-American feels he is a better fighter than lightweight champion Islam Makhachev.During a press conference for UFC 281 last year, Chandler detailed why he believes he would triumph over the Dagestani, saying that he could easily match Makhachev's wrestling and is a better overall striker:"I honestly think my wrestling will stop his attacks. I think I can take him down, I think I can match him grappling for grappling and I think in the striking department, I've got more power, I'm faster and I have better hands... There is not a better wrestler on the lightweight roster than me... I think I match up extremely well, I think I beat him."Catch Michael Chandler's comments below:Chandler currently doesn't have a fight booked, while Makhachev is slated to take on reigning featherweight champion and pound-for-pound king Alexander Volkanovski at UFC 284 in Australia.
