Football fans confronted with increased security at ANZ Stadium for the Sydney FC clash against English football giants Liverpool have been reassured by measures taken by police.

Following the UK terror attack at Manchester Arena on Monday, extra police patrolled ANZ Stadium and no incidents were reported at the game, police say.

While there was no specific threat for Wednesday night's clash, police conducted security assessments and implemented plans with event organisers and agencies to ensure the community was kept safe.

"I spoke to the commander himself this morning and he has assured me that they are looking closely at all the threats, as we would normally," NSW Police Commissioner Mick Fuller told reporters in Sydney before the game on Wednesday.

"We have increased patrols, only on the basis that the community feels safe."

Fans were told to be vigilant and report anything that didn't look right.

"People should continue to go about their lives today, just as they did yesterday," NSW police said in a statement.

British-born Salman Abedi, 22, killed 22 people and injured more than 50 when he carried out a deadly suicide bombing at an Ariana Grande pop concert at Manchester Arena on Monday.
