The standout tie of the round, Manchester United face Arsenal in an all-Premier League clash. Louis van Gaal has been getting a bit of criticism recently as his team hasn't been playing the free-flowing, attacking football that fans had hoped to see when the Dutchman arrived in the summer, and there are some rumours that all is not well behind the scenes. Meanwhile, Arsenal's defensive frailties were highlighted recently in their loss to an unfancied Monaco side who ended up tearing them apart. Arsenal have, however, been more intelligent in their game management in the clashes with the big names this season, and Wenger will more than likely send out his side to try and hit United on the counter, which should make for an interesting spectacle.
