Second row forward Liam Farrell scored his fourth try in eight games during last Friday's 18-14 defeat at Leeds but, more interestingly, has not missed a tackle in any of his matches so far, according to Super League's official statisticians.
Wane is full of admiration for his hard-working back rower but has evidence to counter those stats, and said: "I don't know whose stats they are but they are not mine. He has missed tackles. His defence is fairly good but he still needs to improve a lot. But his attack is great and he has a great attitude. He wants to be better and he is always the first one in my office after games."
He went on: "Everybody is raving about him but our standards are a bit higher than Opta stats and, when he came into the office, he said he was poor.
"As long as I keep hearing that from my players, that's the sort of player I want. As soon as a player says he's happy, then he's gone."
Farrell, a distant cousin of former Wigan captain Andy Farrell, has done more than anybody to help offset the loss of Gareth Hock this year and Wane believes that he can go on to become an England regular.
"Liam can be as good as he wants to be," he said. "He's playing well but he's not playing fantastically well yet. He's going to improve. He's far from the finished article.
"He's a really private, shy lad and he takes it all in his stride. He knows about improving and wanting to get better.
"His skill level and his potential is fantastic and, if he can tweak some small parts of his game, he can go from strength to strength.
"I know he's in the England squad and I can see him cementing his place in his own right for years to come."
