Oliver Glasner maintains the backing of Crystal Palace’s board – despite the Eagles failing to win any of their opening eight games of the season

Oliver Glasner maintains the immediate backing of senior members of Crystal Palace‘s hierarchy but there is increasing alarm at the team’s poor start.

The south London side are one of only four clubs in the Premier League without a victory in their opening eight games – their latest setback arriving in Monday’s defeat to Nottingham Forest, a result that leaves them in the relegation zone.

Palace face Tottenham this weekend – and there is not thought to be any prospect of Glasner’s position being in danger ahead of Ange Postecoglou side’s visit on Sunday.

Nevertheless, Glasner – who is contemplating changing formation – is facing mounting pressure amid concern behind the scenes at Selhurst Park following the team’s difficult start to the season.

Palace face Aston Villa in the Carabao Cup last 16 next Wednesday before league matches against Wolves and Fulham.

And sources are indicating that while the club want to continue supporting the Austrian, if the team remain without a Premier League win heading into the November international break the Eagles board may review their position regarding Glasner.

Palace chairman Steve Parish, who will ultimately decide Glasner’s future, has shown in the past that he is willing to sack managers if the club are in genuine danger of relegation.

There was much optimism heading into the season after Glasner led Palace to an encouraging seven game unbeaten run – six of which were victories – at the end of the previous campaign.

And while last season’s impressive sequence means Glasner has credit in the bank, Palace will consider their options if their struggles continue.

There is an acknowledgement that the departure of Michael Olise to Bayern Munich in the summer arrived as a key blow to the team.

Nevertheless, Glasner will be expected to make the necessary improvements to revive the team’s fortunes following their disappointing start.

It is understood Glasner has explored a tactical switch in hope of turning results around.

The Austrian has relied on a a five-man defensive system, but it is understood the coach has looked at the possibility of deploying a back-four in recent days with a view to unlocking the team’s offensive game.
