Jeff Jones’ team go in search of their first win of the season and, like their hosts, have a 0-2 record.
Aliu (pictured) said: “As a team we all need to look at defensive positions and starting out a lot more aggressive and not waiting until we are down before we decide to play.
“Cheshire are always a tough team to play at home and I don’t expect any difference this season.
“On paper they have a very big team so it’s important we gel as a unit defensively this week in training.”
Giants were beaten by London Lions and Sheffield Sharks last weekend, while Phoenix also suffered against the Sharks before taking a bad beating from Newcastle Eagles.
Coach John Lavery said: “We didn’t start well against Newcastle and from there we were fighting to claw it back.
“We came out of the blocks really slow. They built up a 25-point lead in the first quarter and that killed us.
“Manchester have kept the nucleus of their team together and they have made a couple of changes.
“We know exactly what they are about and what they do.”
