Marquee signing Harry Kewell will be part of lethal front four at Melbourne Heart Harry Kewell has fronted the media for the first time as a Melbourne Heart player, confident that he can make the difference for the A-League side this season. HARRY Kewell will form part of what could be a potentially lethal front four at Melbourne Heart this season. Coach John Aloisi said today he had not settled on what position his new signing will play, but said to have Kewell in combination with fleet-footed attackers Gol Gol Mebrahtu, David Williams and Mate Dugandzic was highly appealing. Heart struggled for goals last season, its tally of 31 was two shy of the A-League's least prolific club, Perth Glory and 17 less than both Central Coast Mariners and Melbourne Victory. Kewell scored eight times for Victory in 2011-12. "Harry can play anywhere in the front four," Aloisi said this morning. We play with quite an attacking team and I see him as one of those players that I can put in anywhere. With the attack that we've got at the moment with Gol Gol Mebrahtu looking as good as ever - he's got over a lot of his injury problems and is looking sharp and lightning quick as ever - David Williams, Mate Dugandzic, Ben Garrucio, we've got some attacking power. That's only going to help Harry and Harry will help them. I haven't decided which position he'll play exactly, but there's a long pre-season to sort that out. Kewell himself said he was happy to play wherever he is needed. "I think in this day and age of football you've got to be able to play in three or four positions," Kewell said. You start in one position and 90 per cent of the time you end up not playing in that position come the final whistle. If he has options I think it's great and I just want to do what's best for the team, whether that's up front, left, right, behind, midfield, defender, you've just got to do the right thing for the club. The 34-year-old joined his new teammates at AAMI Park this morning for his first training session as a Heart player. Kewell denied he would have retired had the Socceroos not been in contention to make next year's World Cup in Brazil. Kewell will form part of a formidable front four for Heart.
