Chelsea are experiencing some hefty difficulties under Maurizio Sarri after a bright start to life under the Italian.
Early season form suggested that the Blues could be potential Premier League contenders.
But since the turn of the year, Chelsea have seen their weaknesses badly exposed and are looking likely to lose the fight to stay in the top four.
The Stamford Bridge side have conceded four goals in consecutive away games, losing to the likes of Tottenham, Arsenal, Bournemouth and now Manchester City.
It leaves them looking perilously at the Premier League table, with Arsenal and Manchester United in the ascendancy.
A finish out of the top four cost Antonio Conte his job last year, despite securing an FA Cup in his final match in charge.
And many reckon Sarri could fail to last longer than this season, with the latest defeat even suggesting that he could be gone before the year is out.
But former Arsenal star Parlour reckons that a decision will be made at the end of the season.
“Every single manager is under pressure,” Parlour told the Daily Express.
“You don’t get time in football, you certainly won’t see a Sir Alex Ferguson or Arsene Wenger with 20 years again.
“We know, financially, that getting into the Champions League is so important.
“It’s an interesting one, I really can’t work Chelsea out sometimes.
“They go to Bournemouth and lose 4-0 and then can play really well [vs Huddersfield].
“I hate to see managers get sacked so early. Chelsea have got to give Sarri until the end of the season and then assess the situation.
“If they come sixth or fifth, then maybe it’s not good enough and Sarri knows that.
“Every manager is looking over their shoulder, a couple of bad results and then you’re out the door.
“Chelsea are still playing for big, big trophies. There’s so much to play for, and you’ll be looking who has won the trophies too.”
