Boss Lennon said a few days later: "I understand the frustrations of the supporters because ultimately we are not in a great run at the minute but it serves no purpose, particularly for the players."

After losing 4-2 to Serie A leaders AC Milan in their Europa League dead rubber in the San Siro on Thursday night to leave the Scottish champions with just two wins in 11 matches in all competitions, the  Northern Irishman turns his attention to the Premiership.

St Johnstone are the visitors for another game played in front of no fans and Lennon will be looking for his side to keep on the tail of Rangers who have an 11-point lead at the top of the table, albeit the Hoops have two games in hand.

Asked about the prospect of supporters turning up again this week to express their frustration at how the season is going, he said:

"Well, hopefully they will be celebrating a victory because that is what we will be trying to do. As we always do.

"I touched on what I thought of it on Sunday and if it is going to be reminiscent of Sunday, it is not what we need or what the players need at the minute."

A busy December sees Celtic play home league games against St Johnstone, Kilmarnock, Ross County and Dundee United, as well as a trip to Hamilton, and there is also the final Europa League group game against French side Lille and the William Hill Scottish Cup final against Hearts at Hampden Park.

Lennon believes that regardless of venue Celtic need to find a winning formula quickly and he took encouragement from their performance in Italy.

The former Celtic captain, in his second spell as manager of the Parkhead club, said: "Home or away, it doesn't matter.

"We have to put in performances that reach the levels we reached last night.

"I saw plenty of signs last night that we are more than capable of that which please me."
