Arsenal manager Jonas Eidevall said his players adapted "brilliantly" to a new tactical system he utilised to beat Man City in the Conti League Cup semi-final.
Arsenal booked a spot in the tournament final for the ninth time as forward Stina Blackstenius came off the bench to score an extra-time winner, which deflected past Sandy MacIver. Eidevall employed a variation of a 3-5-2 system with Leah Williamson redeployed in defence and Katie McCabe and Laura Wienroither occupying the wing-back roles.
Although they were second best in the first 45, McCabe and Wienroither got to grips with City's wide forwards Chloe Kelly and Lauren Hemp as the game wore on. Arsenal created the better chances in the final half an hour and should have won the tie in 90 minutes, but Lina Hurtig and Blackstenius failed to convert from good positions.
