Hibs league form concerns former boss Mixu Paatelainen
Hibs need to display more fighting spirit to pull away from a relegation dogfight, according to former manager Mixu Paatelainen.
Sunday's 5-0 defeat at home to Celtic means Hibs are level on points with basement side Dunfermline with a game in hand.
"It's a very alarming situation they're in," Paatelainen told BBC Scotland's Sportscene programme.
"They need to tighten up. Hibs have plenty of firepower to score goals."
Paatelainen, now in charge of the Finnish national side, left the Edinburgh club by mutual consent in May 2009 after 17 months in charge.
He then moved to Scottish Premier League rivals Kilmarnock where he was voted the league's manager of the year.
"Dunfermline have plenty of fighting spirit and are level on points at the moment, although Hibs have a better goal difference," said Paatelainen.
"Goalkeeper Graham Stack didn't have the best of days [against Celtic].
"Looking at the performance I didn't see any real fighting spirit from Hibs players. In previous matches their defence has been much more solid.
"They were wide open all over the pitch and Celtic passed the ball for fun.
"Dunfermline play as a unit and it's a real dogfight."
Current Hibs boss Pat Fenlon says the bruising defeat by Celtic should act as a warning to the Easter Road squad.
"We've got a bit of praise for the two games, we've gone through in the Cup and 0-0 with Aberdeen, but you can't take that and sit on your laurels and hope things will happen for you," Fenlon told BBC Scotland.
"You've got to keep working hard to change things and turn it around.
"It's a wake-up call for everybody. We're in a very dodgy situation."
