Concerned Kris Commons believes Mikael Lustig 's Rangers pop could be used against Celtic in the Ibrox side's quest to stop 10 In A Row.
The Swede loved nothing more than to wind up his rivals during a trophy-laden stay in Scotland before departing for Genk last summer.
And Lustig cranked up the pressure further as he claimed Steven Gerrard's men will go down as "the worst team ever in their history", if they fail to stop the historic title haul.
The 33-year-old was lapping up the celebrations as Celtic secured a ninth consecutive title after the Premiership campaign was concluded amid the COVID-19 pandemic.
But Commons reckons his old Celtic pal may have overstepped the mark and believes the Rangers boss will use those comments as a source of inspiration.
Speaking to the Daily Mail, he said: "Mikael Lustig is one of the nicest guys you will ever meet. He is one of those players who came from abroad and just gets the banter in the UK.
"But when I saw his comments, I thought: 'I see what you are saying but Steven Gerrard will be pinning that up in the dressing room on the first day of pre-season training for motivation'.
"One of the best things Garry Parker did was before a second leg against Shakhter Karagandy in the Champions League.
"We were 2-0 down from the first leg and heading into the Europa League qualifiers unless we beat them 3-0 at Celtic Park.
"Neil Lennon didn't say a great deal that day but Garry put a paper up with their manager saying he had booked his flight to the Champions League draw.
"Two-nil in the first leg? In their mind, it was finished, done!
"We looked at that paper and we didn't need tactics or a team talk.
"We just went out there and gave it everything. There was anger there. Don't you ever write us off.
"So my initial thought (On Lustig's words) was: 'Don't rev them up'.
"But I'm sure Celtic will approach next season in the right frame of mind."
