Paul Roos not fussed that Jack Trengove explored trade options to Richmond Jack Trengove could have been traded from Melbourne to Richmond if it wasn't for his footy injury. MELBOURNE coach Paul Roos insists he doesn't have to repair his relationship with Jack Trengove despite the midfielder's aborted trade to Richmond. The Demons were happy to offload Trengove for pick 12, but more surgery on his career-threatening navicular injury means he now has to stay put. Roos, speaking on the first day of a pre-season he promised would be brutal, said Trengove was never part of any "fire sale." The Demons coach hasn't met with Trengove since the trade fell through. It was never a case of him being thrown out there and that he wasn't going to play for Melbourne. It was "Here's an opportunity for us and for him, is he comfortable with it?" and he was comfortable with going to that next stage," Roos said. We were really clear with our players when they left (for holidays) that we needed to get better. I spoke to Jack directly and we were really clear with him that he was a required player. Then there was an opportunity that Richmond presented to us. Melbourne's Jesse Hogan returned to training. I've texted him (Trengove) a couple of times while I've been away and I'll catch up with him as soon as I can. I don't think there's any problems there whatsoever. Trengove, who will spend the next six to eight weeks back in a moon boot, will miss a pre-season program Roos vowed would hit his players hard. It's going to be tough. We need to continue to improve and improve significantly to keep up with the lower end, let alone bridge the gap to the top end," he said. Paul Roos and Simon Goodwin oversaw Melbourne's first pre-season training session. I think pre-season is just going to get harder and harder for the players and I'm sure they're aware of that. The game is going to another level again. We saw Hawthorn's effort in the Grand Final with the tackling and pressure and run and we've seen where Port have taken the offensive game. The players aren't going to be in for a relaxing six weeks. Roos admitted there would be tweaks to the Demons" goal-shy approach, acknowledging he "overcorrected" to a more defensive system. New Demon Sam Frost trains with his Melbourne teammates. "But we had to; we were leaking 122 points a game or something and you're not going to many win games - Melbourne won two - leaking 122," he said. We did that well ... but we need to get better at moving the ball quicker and scoring. Ultimately, good teams need to score and put pressure on the opposition as well. The theme is more finding a balance between the two. Melbourne has picks 2 and 3 in this month's national draft, but on Wednesday completed the signing of Power discard Ben Newton - another player in his early 20s with AFL experience to join the club. Brendan McCartney, Melbourne's newest addition to the coaching staff, with Josh Mahoney. It probably follows the theme from last year of trying to get a mix of younger guys, but not too young. We've obviously got picks 2 and 3 in the draft, but we don't see picks 2 and 3 as the saviours of the footy club," Roos said. The pressure can't be on young kids coming to footy clubs. They've got to come in and develop and I think the Melbourne players have been short-changed here and we're changing that and want to make sure that doesn't happen again.
