Who starts as Celtic bid to preserve astonishing success rate?published at 15:56

Who makes Celtic's cup final team?
Firstly, some stats. Celtic manager Brendan Rodgers is undefeated at Hampden. His record reads: played 14, won 14. He's also unbeaten at Murrayfield, where the 2018 League Cup semi-final win over Hearts took place.
Celtic haven't lost a Scottish Cup final in 23 years, winning all 11 since the 3-2 defeat to Rangers in 2002.
Celtic haven't lost a final of any kind since Kilmarnock beat them to lift the 2012 League Cup. The Parkhead side have contested 15 finals since and come up smelling of roses in every one.
So to whom should the manager turn to preserve such an astonishing success rate? I'll give you my team.
The goalkeeper and back four is the easy part. I'll be very surprised if Rodgers deviates from Kasper Schmeichel in between the sticks with Alastair Johnston, Cameron Carter-Vickers, Liam Scales and Greg Taylor in front of him.
It wouldn't appear that Auston Trusty has done enough to oust the reliable Scales from the Hampden starting XI.
Midfield is an area where Rodgers has a couple of decisions to make given the absence of creative playmaker, Reo Hatate.
Captain Callum McGregor is nailed on to start. There are two spots up for grabs alongside him with three players crossing their fingers: Arne Engels, Paulo Bernardo and Luke McCowan.
Rodgers has made no secret of his soft spot for Engels, a player he was happy to break the club transfer record for last summer.
However, the midfield that helped tear Aberdeen to shreds at Pittodrie recently had Bernardo and McCowan just ahead of McGregor. If Engels and Bernardo are paired with the skipper, I wonder if that trio is a bit too 'samey'?
McCowan brings more of an inventive spark, not to mention an eye for goal. While Rodgers is more likely to go with McGregor, Engels and Bernardo, this correspondent would plump for McGregor, Engels and McCowan.
Which leaves the front three. Daizen Maeda, Scotland's player of the year, is already on the teamsheet. Two options for him: wide left, to allow Adam Idah to start as main striker, or up front on his own.
One person who deserves to start is man of the moment, James Forrest. He terrorised the Dons last midweek and was man of the match against St Mirren on trophy day despite only playing half an hour.
The club's most decorated player will be eyeing up the 27th piece of silverware of a fairytale Celtic career.
Who drops out to accommodate him? Nicolas Kuhn's form has been patchy at best this calendar year.
With Maeda bombing down one wing and Forrest patrolling the other, the physical presence (and 20-goal contribution this season) of Idah might just complete Rodgers' ideal line-up.
The Republic of Ireland frontman got the winner in last year's final and has hit a hot streak lately, scoring six in six games.
My Celtic cup final line-up would therefore be: Schmeichel, Johnston, Carter-Vickers, Scales, Taylor, Engels, McGregor, McCowan, Forrest, Idah, Maeda.
Feel free to disagree - and tell me yours.
It may well transpire that Rodgers starts Bernardo and Kuhn and keeps McCowan and Forrest as impact substitutes. Whatever the line-up, it will take a mightily improved Aberdeen showing just to make this final competitive.
