Although the match will be a friendly, but the national teams of Scotland and England are principled rivals, so they are unlikely to play with fully reserve squads.
Scotland is now quite strong, in the qualification group the national team won all 5 matches, and against Spain. England have one of the strongest squads in a long time, but still have problems in defence and at the goalkeeper's position.
Prediction: at least 3 goals to be scored. We recommend the "Over 2.5" bet, odds 1.96
