VIDEO: "We’ve worked very, very hard" - Williams

Melbourne Heart FC winger David Williams believes intensity at Heart training this week has given his side the best possible preparation for Sydney FC.

Off the back of a disappointing 3-3 draw against Newcastle Jets, Melbourne Heart FC winger David Williams believes that the quality, determination and intensity on the training track has illustrated Heart's hunger for three points this week.

Facing Sydney FC at Allianz Stadium on Sunday, Heart will enter the match with the expectation three points will be achievable, but the side will be wary of a Sky Blues outfit who received a necessary shot in the arm with the appointment of Frank Farina as coach during the week.

“We-ve worked very, very hard," Williams said.

"Our conditioning session showed it on Tuesday and we-ve just worked as hard as we can. There are things we have to work on but they-re only little minor things.

“The response in training has been excellent so hopefully we can take this week of training into the game on Sunday.”

With three key players in Aziz Behich, Richard Garcia and Michael Marrone missing on Sunday through international duty, Aloisi is likely to ring in the changes, giving a host of young players the opporunity to shine for the senior ream.

Possible replacements include Sam Mitchinson and Ben Garuccio, while Jeremy Walker and Golgol Mebrahtu could debut against Sydney.

“The good thing about that [the squad changes] is that players who haven-t played before, they have that energy to come in and that excitement so usually that gives something good," Williams said.

“I definitely think we-ve got the depth for players to step in so if we can actually work as a team then I don-t think anyone has a problem with the players stepping in doing a bad job at all.”

While Williams said he is confident the side can get a good result this weekend, he admitted, tongue in cheek, that Alessandro Del Piero could be a a player to watch.

“Some little guy number 10 I think he is. He-s stood out for them every single game but as I said the structure that they have isn-t quite there so it-s going to be unpredictable," Williams said.

“It-s going to be a tough game but I definitely think we can come away with the three points.”
