Paul Pogba has demanded his Manchester United team-mates continue to demonstrate their mental strength against Arsenal on Sunday. They had a quick, powerful team with big lads like Patrick Vieira, Sol Campbell, Edu, Pascal Cygan, and, at Highbury especially, you were aware just how small the pitch was when you were up against big players.

The quandary for Bellerin will be to reel in his electric dashed down the United left, keeping Sanchez as his bedfellow for the majority of the 90 minutes at Old Trafford.
And now he has dropped a fantastic bombshell by revealing he once held talks with Manchester United about taking over as manager when Alex Ferguson was set to retire. Goalkeeper Sergio Romero however, is out with a knee problem.

One of Arsene Wenger's darkest moments in charge of Arsenal, and at a time when some of the Gunners' fanbase really started to question the leadership and authority of a man who had given them so many sensational triumphs in English football.
Sanchez could indeed be the "X" factor this weekend, and it will be interest to note what sort of reaction he gives should he find the net.
The result brought an end the Arsenal's monumental "Invincibles" run as they were one game away from making it 50 Premier League matches without defeat.
