Celtic FC embarrassingly crashed out of the Champions League qualifiers as they went down 4-3 to Romanian champions Cluj at Parkhead.
The Bhoys went 1-0 down right before the half-hour mark but in all fairness, they fought well and eventually took the lead on the 61st minute courtesy of Edouard.
But it was their defence that led Celtic down and many are claiming that this has been one of their worst performances in recent memory.
And speaking about the loss, Rangers boss Steven Gerrard warned his side to no make the same mistake as their Glasgow counterparts did.
He said(as reported): “What last night shows is that European ties are never over, even when you get a positive result in the first leg.
“Some of these teams that people don’t know much about — Cluj from Romania, for example, or Midtjylland from Denmark — they carry a huge threat.
“They’re so desperate for financial reasons to progress, like most of us, so my players need to take note of last night and make sure we deal with our second leg much better.
“It’s certainly going to be detrimental because all the Scottish teams need to do as well as we can to improve the coefficient and give ourselves an advantage in these European competitions.
“From that aspect, [Celtic’s defeat] is very disappointing.
“But for me, I’m the manager of Glasgow Rangers and my focus is on the challenges that face us.”
And these statements from Gerrard has been met with mixed responses with many claiming that the manager was just trying to rub salt in the wounds of Celtic FC.
But others though think that he wanted to use this example in order to motivate his players before they take on Midtylland in the Europa League qualifiers on Thursday.
