Fremantle coach Ross Lyon says Dockers have' plenty of improvement' left IMPROVEMENT COMING: Fremantle coach Ross Lyon says his side has only been operating at 70 per cent. FREMANTLE coach Ross Lyon has warned his unbeaten Dockers have only been operating at "70 per cent" so far this season ahead of tomorrow night's showdown with Essendon. "We reckon we've been at about 70 percent, so we've got plenty of improvement," Lyon said. And that's the aim, to improve, because there's some top-line teams that we're going to be playing. Lyon said he did not know how the Bombers would react at Patersons Stadium tomorrow night following fresh claims coach and club legend James Hird was injected last year with a substance banned by the World Anti-Doping Agency. "I think we all understand that there's a serious issue being investigated," Lyon said. There's reports pending, so from my position I think you leave it to the correct authorities and wait for the outcomes. My role is to coach the Fremantle Football Club and focus on us and when that ball's bounced have the team prepared and ready to play. I haven't got the luxury to be worried about anything outside of this football club. But Lyon said he expected a strong challenge from the top-of-the-table Bombers. I think they're in superb form. We see it as a really strong challenge against a quality team and they've set themselves for us," he said. I think James (Hird) spoke about it straight after their last win, so we understand what's coming. It's going to be a fierce battle and it's a real opportunity for us to improve and test ourselves. We want to overcome that challenge and be 3-0, but there's plenty of work to do. Lyon is likely to send tagger Ryan Crowley to in-form Bombers skipper Jobe Watson. "We'll give him the respect he deserves," he said. He's a reigning Brownlow medallist, captain of their club, B&F winner, who's an elite player of the competition that needs plenty of time put into him. He's quite unique. He goes forward, so do you go all the way with him or do you hand over (to a defender)? They're things we're still working through.
