Arsenal manager Mikel Arteta has warned his players that they must prevent Real Madrid attackers Kylian Mbappe and Vinicius Junior from receiving the ball in dangerous areas.
Arsenal were preparing for a major Champions League quarter final encounter against the Spanish giants.
The presence of Mbappe and Vinicius represented one of the biggest threats facing the Gunners.

Both forwards possess exceptional pace and technical ability and can change the outcome of matches with individual moments of brilliance.
Arteta understands that allowing either player to receive the ball freely could create serious problems for Arsenal’s defence.
The manager therefore urged his players to remain organised and limit the space available to Real Madrid’s attacking stars.
Arsenal would need a disciplined performance across the pitch if they were to compete successfully against the European champions.
The Gunners had been preparing carefully for the high profile encounter and were aware that small mistakes could prove costly.
Arteta will also rely on his own attacking players to create problems for the Madrid defence.
The Champions League quarter final represented a major opportunity for Arsenal to demonstrate their progress under Arteta.
