The 4 things Rangers can change against Celtic as Neil Lennon ditches Philippe Clement feud to turn surprise advisor

Baffled Neil Lennon has warned Rangers boss Philippe Clement he MUST shake things up for the Scottish Cup Final - because his team isn't "good enough to play football against Celtic".

The Belgian boss is winless against the Hoops since he stepped into the hot seat - and after letting the Scottish Premiership title slip through his grasp Clement will have one final crack at Celtic before the summer shutdown. The Light Blues boss will look to seal a cup double at Hampden and beat Brendan Rodgers to the silverware - but newly appointed Rapid Bucharest boss Lennon insists that he must shake things up to pull off a derby day win.

The Irishman has previously locked horns with the Rangers boss this season when Lennon questioned whether their rivals have the correct mindset to topple the Hoops this term - with Clement firing back at the Celtic legend that the barb had only served to motivate his side. However, Lennon appeared to drop the feud to offer Clement some advice before the showdown at the national stadium.

The ex-Celtic boss told PLZ that Clement must look at changing the personnel and the formation during the clash with the Scottish champions. He urged the Ibrox gaffer to look at breaking the dominance of Celtic on the ball by adding two attackers - as well as providing cover for James Tavernier at the back.

Lennon said: "He (Philippe Clement) has got to change it. Whether you change the formation or the personnel - he can't go with the same formula because it's not working.

"Celtic are too good. For me, how do you get Tavernier further forward? You need to stop worrying about what (Daizen) Maeda is doing. Do you play three at the back? Or two strikers to stop Celtic playing out from the back. That's what I would do - because whatever he has done this year hasn't worked and he can't stop the flow of Celtic's passing moves.

"I don't think this team is good enough to play football against Celtic. They lack speed, they lack creativity - so play to your strengths. Dessers does OK at times up there on his own but in the wider areas I think they have been poor.

"I think at centre-half they have been struggling against Celtic as well. For me, O'Riley, Hatate and McGregor dominated the last game and it could have been a lot more. I think the 2-1 scorelines have flattered Rangers and there has been a gulf between the teams. Philippe has to find a way of closing that gap by hook or by crook."
