Melbourne Heart coach John Aloisi ready to soak up the pressure against Adelaide United Melbourne Heart coach John Aloisi is currently under pressure but knows Adelaide United is vulnerable. Picture: Robert Cianflone. JOHN Aloisi says lining up for that famous penalty kick in 2005 for the Socceroos is the sort of pressure he has become accustomed to. But the Adelaide-born former Socceroo and current Melbourne Heart boss says there's no denying that he's under pressure to beat Adelaide United at AAMI Park on Sunday. Heart hasn't won an A-League game since beating Sydney FC 3-1 in February. "That pressure as a player has put me in good stead as a coach," Aloisi said. That (Socceroos) penalty was massive but also I have been involved in relegation battles that's life or death where you've lost five on the trot and all of a sudden you need to beat Real Madrid at home to stay in touch or face relegation. I wanted to succeed as a player and that's no different as a coach. I can't do much about the outside pressure it's the processes we need to get right. Melbourne Heart sit bottom of the table and remain without a win. Kick Off asks how long will John Aloisi remain in charge? Adelaide, however, has had the knack of giving two under fire bosses breathing room this season. Newcastle Jets boss Gary van Egmond and Melbourne Victory coach Kevin Muscat were both under critics' scrutiny before meeting Adelaide but wins over the Reds (2-1) and (3-0) has cut those chiefs some slack. But Aloisi believes Heart is a win away from turning its fortunes around. "We have to start getting results and this is a massive game for us," Aloisi said. Everyone is disappointed the entire club, our members, no one wants to be in this position but we are and we need to stick together. We have to fight our way out of it and we do know a win can change things very quickly. Adelaide, however, has impressed Aloisi at least in the sense that when the ball is kept the Reds can do it for long periods to frustrate the opposition. But Adelaide must also be wary of Heart's Maltese international striker Michael Mifsud. Mifsud is also due to break his A-League goals duck given "The Mosquito" has come close this season. And Aloisi is not one to whinge. He didn't want to make excuses for his side's slump despite that fact he has lost seven of his ideal starting XI players to injury including Orlando Enegelaar (fractured tibia), Patrick Kisnorbo (knee), Harry Kewell (whiplash and ankle), Dylan Macallister (hamstring) and Jonatan Germano (hamstring and calf), Nick Kalmar (quad and calf) and Andrea Migliorini (knee) over the course of the season. However, Aloisi said Kewell would probably play a role off the bench. "It's still not 100 per cent (Kewell's ankle) but the swelling has gone down," Aloisi said. Now it's just making sure the ankle is strong and that's he is confident on it. Hopefully he'll be available but probably unlikely to start. AAMI Park on Sunday, 4.30pm Live on Fox Sports
