What might Scotland change for Ivory Coast test?
Regulars John Souttar and Grant Hanley are the most likely candidates to start, but Wrexham's Dominic Hyam is another option. At right-back, Nathan Patterson looked rusty before being replaced by Anthony Ralston on Saturday. Clarke knows exactly what those two offer, and with first-choice Aaron Hickey still out injured, could there be a start for versatile Bristol City defender Ross McCrorie?
Captain Andy Robertson and Kieran Tierney will likely share the left-back duties once more.

With Ben Gannon-Doak missing through injury, Tommy Conway started on the left, where he has impressed at times this season for promotion-chasing Middlesbrough.
The 23-year-old was singled out for praise by Clarke after the game, despite himself admitting he struggled to get into the contest early on. He was replaced by teenage Kilmarnock winger Findlay Curtis on 81 minutes, but the on-loan Rangers man struggled to get any meaningful touches on his senior international debut. Given the lack of wide options at Clarke's disposal, it will almost certainly be those two vying to start on Tuesday.
In the heart of midfield, there might also be a slot for 19-year-old Udinese midfielder Lennon Miller. The former Motherwell player has become more of a feature in Serie A since the turn of the year and he will fancy his chances of a fifth Scotland cap at Everton's Hill Dickinson Stadium, especially given both Lewis Ferguson and Kenny McLean played the full 90 against Japan. Bournemouth's Ryan Christie and Sparta Prague's Andy Irving are the other central midfielders who started on the bench against Japan, with only Christie getting game time.
Findlay Curtis made his Scotland debut against Japan It feels like every time Scotland play, there is a debate surrounding the best option up front. Lyndon Dykes started against Japan and toiled hard without much joy. The Charlton man provides physicality and endeavour and will pop up with the odd goal here and there - his record of 10 in 49 caps is not to be sniffed at.
