Expressing surprise at the comments about a tie Celtic lost 4-2 on aggregate, O’Neill said: “So he is picking our team? Well done old Danny. He’s only in less than a year.

“I have to laugh. He’s made a comment about the picking of our team? Absolutely extraordinary. He hasn’t been in Glasgow long.

“There’s no need for him commenting on my team.”

However, what appeared to get O’Neill most irritated was the Rangers boss’ suggestion that: “I was a little bit surprised after 1-0 that they’re not trying to win this game, 2-0, 3-0, to have a chance. They keep the result until the end.”

The Northern Irishman replied: “He wants to be involved in some of these games.

“I didn’t see it like that. We were driven back because they are a very good team and in the top four of the Bundesliga.”

All that after Rohl had insisted: “I think, in general, it makes no sense to speak too much about the other side, we have to focus on ourselves.”

Hence the battle lines have been drawn for a Glasgow derby that could be of crucial importance to the destination of the Scottish title.

Heart of Midlothian are currently four points clear of Rangers at the top of the Premiership and Celtic two points further back with a game in hand.

O’Neill does not think the comments will add any fuel to what is usually a firey fixture.

He should know. Although it will be his first league Old Firm derby since a 2-1 win at Ibrox in April 2005, he has won eight of his last 10 against Rangers, losing just two, and also led them to a 3-1 League Cup semi-final win over Rohl’s side in November.

That was in his first spell as interim manager, but Rangers reversed the scoreline at Celtic Park in January, a result that went some way to ushering in his second after the sacking of Wilfried Nancy.

Celtic’s first-ever win in Germany came after a 2-1 loss at home to Hibernian dented their domestic title hopes.

“We are running out of games,” O’Neill admitted. “We have been trying to catch up for quite some considerable time and we’re still trying to do that.

“Losing to Hibs was a setback, but it wasn’t mortal and we’re still there.”

Now he is relishing a “really great fixture” he “never expected” to be involved in again.

“He [Rohl] possesses a fine team over there and it is going to be tough for us to get a result,” O’Neill admitted.

“In normal circumstances, you would like the full week to prepare, but we’ve gone to Ibrox and won before after we have played midweek games.”
