CELTIC captain Scott Brown liked a fan's savage tweet about Neil Lennon in the wake of the club's Champions League exit.
The Hoops were dumped into the Europa League play-offs after Romanian outfit CFR Cluj's shock 4-3 Parkhead victory.

Boss Lennon surprised many by dropping £3million left-back Boli Bolingoli and £7million centre-half Christoper Jullien for the club's decisive third round qualifier.
Influential midfielder McGregor was instead shunted to left-back, while Hatem Abd Elhamed returned from a leg knock.
But the Parkhead gaffer's gamble didn't pay off as the Scottish champions blew the chance to move within two games of the lucrative group stages.
The team was booed off the park at full-time and angry fans immediately vented their anger on social media – with Lennon and the Celtic board coming under fire.
And skipper Brown – who conceded a penalty with a foolish handball – appeared to agree with one supporter's brutal verdict on Twitter.

However, Brown has since 'unliked' the tweet and sent out an apology to dismayed supporters – insisting it was a mistake.
Brown – who gifted Cluj a second-half penalty with a handball – tweeted: "Was just flicking through Twitter must of touched the button by accident.. Not my style to slag anyone off on Twitter.
"I am fully behind the manager and all the players are as well. If anyone should be getting a slagging or a abuse it’s all on me tonight as didn’t perform. Sorry."

Meanwhile Chris Sutton has blamed Celtic's transfer policy for the club's Champions League KO.
The Hoops banked £25million from Kieran Tierney's sale from Arsenal – money that will now swell the loss from Champions League revenue.
And Sutton tweeted: "That's the Tierney money gone tonight… the messing about in the last few windows has bitten Celtic on the backside… this day was always coming…"
