Celtic boss Tony Mowbray admits his team often have to overcome their own anxiety as much as the opposition at Parkhead.
Saturday's 1-0 win over Dundee United was well deserved but it was a nervy ending before Hoops fans could celebrate a win that Robbie Keane's first home goal since he arrived on loan from Tottenham this month gave them.
However, asked about the anxiousness which envelopes Celtic Park at times, Mowbray replied: "That's been there since day one, has it not?
"The team didn't win the league last year and there is an anxiety in the stadium but the players have to deal with that.
"We have found on several occasions this year that once you score the second goal, the anxiety disappears, the crowd enjoy the event and everything loosens off.
"(Yesterday), we didn't manage to get that second goal and so the anxiety remained.
"But at the end of the day we won the match and got the points."
