Kevin Mitchell needs to prove himself ready for world level with a win against Karim El Ouazghari on Saturday, says Alex Arthur.
The Essex-born lightweight contender has joined ExCel Arena bill and is looking to build on his last two wins against Sebastien Benito and Marco Lopez respectively.
Mitchell took nearly a year out after defeat to Ricky Burns in Glasgow last September and the Ringside panel believe the 29-year-old has to prove himself this weekend to stand a chance of getting back to world level.
Former super-featherweight WBO king Alex Arthur told Johnny Nelson and Adam Smith: "He certainly looks like [a potential world champion].
"He's climbed back up the ranks since that Burns loss and I'm hoping that we can see Kevin back up at world level. If we can prove himself on Saturday night he deserves another shot."
Mitchell has rejoined his former trainer Tony Sims and signed with Eddie Hearn's Matchroom Boxing, something former British, Commonwealth and European champion Jamie Moore believes is a big step towards getting his career back on track.
Moore said: "He seems to be rejuvenated and talking about learning from big fights. Kevin's fought at world level twice and fell short by quite a way so he won't be happy with that.
"He's new to Eddie [Hearn] so he's taking a massive step, but he seems to have really come into his own at a late stage in his career. If he's comfortable with Tony [Sims] he'll be much happier."
