Could be starting 4-3-1-2, switching to 3-5-2/3-4-3 after an hour with Duffy on for Montoya, Trossard for Alzate/Gross and Murray for Connolly.
Or, it could be something totally different with different people coming on in different positions
Suspect it’s going to be a 4-2-2-2 as normal but you never know with Potterball?
