Sydney FC coach Frank Farina has been reassured by the club's chairman that his job is safe until at least the end of the season despite the Sky Blues' recent poor run of form and lacklustre performances.

Chairman Scott Barlow has put his faith in Farina to turn the club's form around and will continue to support him throughout the remainder of the season despite the club's rapid slide down the table.

Sydney's coach has come in for criticism in recent weeks having collected just one point from a possible 15. The team's performances since the start of December have drawn the ire of many fans and their fury erupted at Allianz Stadium on Saturday night after the 1-0 loss to Central Coast Mariners, their fifth defeat in seven games.

Fans booed their team at the final whistle and chants demanding a change echoed around the stadium. Other supporters voiced their dissatisfaction on social media.

However, Barlow yesterday reaffirmed his faith Farina could turn the club's fortunes around and clinch a top-six finish.

''That's certainly our intention and as I think is widely understood, Frank has got a contract for this season and next. Next season is contingent upon a couple of things,'' Barlow said.

''Frank will always be the first person to hear about any concerns I have and I certainly haven't had any conversations with Frank. [I have] No intentions for any change.''

Farina slammed the performance of a number of his players following the loss to the Mariners and vowed to drop those who didn't show a fighting spirit after conceding in the 58th minute.

Farina didn't identify any players specifically but was furious with the team's lack of fight in the second half and a drop in mentality of a number of individuals who may be omitted for next week's match against Melbourne Victory.

''I expected a better reaction after the goal and if I'm not going to get that then I'll try players that hopefully will,'' Farina said after the match. ''Tonight was a good opportunity to jump back in [to the top six] and we didn't do it. Some of the performances weren't as good as I expected - without naming individuals - so if we have to change, we'll change. It's about winning games of football and getting points. I'm not happy with that tonight.''

The Sydney coach didn't hide his frustration after his second successive defeat without scoring and has made no secret of his disappointment in the attitude of some players.

''Disappointing I think in one word. I think we played some decent stuff in patches, most probably could have scored just before they scored with a deflected goal but our reaction after that, I expect more. I was disappointed in that,'' Farina said.

He was critical of a high number of individual errors and unforced mistakes that broke down many of their attacking plays.

''We have to cut the basic errors out like poor passing and poor control and if you minimise those errors you will have a lot more of the ball. When you have a lot more of the ball, you score more goals,'' Farina said.
