3. Youthful energy

One of Arsenal's biggest faults in last week's first-leg defeat to PSG was their lack of energy with their slow-paced play easily dealt with by the opposition.
The Gunners can not afford to repeat that at the Parc des Princes and may have to make some changes to the team to prevent it from happening. Nwaneri could be the spark needed to ignite the fire in the side.
His youthful bursts of energy, whether from midfield or on the wing, would be of great help to Arsenal as it would allow them to dominate the game rather than be forced to sit back and soak up pressure. Nwaneri could be a key factor in the Gunners controlling the proceedings.
