Cunha & Mbuemo very lively. Have willing runners in possession and on transitions. Saw some patterns in possession that bode well for future - Time on training ground showing. Negatives: Cheap goal, GK gotta do better. Be aggressive in transitions if Bruno playing deeper. 1st thought to creep forward… lapses in concentration may be a problem against the better and more physical teams. Didn’t flood the box enough at times (however, Sesko may change this).
