Arsenal vs Tottenham Hotspur: 5 key battles to watch out for

#2 Alexis Sanchez vs Jan Vertonghen

Tottenham Hotspur v Arsenal - Premier League

Like his teammate Ozil, discussions surrounding Alexis Sanchez have mostly involved his future at Arsenal, and not nearly enough has been said about his contribution to the team this season. The Chilean hasn't been in the best form this season, scoring only the solitary goal so far. While his impact on the game should not be measured merely in terms of the goals he scores, his performances, as against Manchester City, simply haven't been up to the mark.

His adversary on Saturday will most likely be the impressive Jan Vertonghen. In the absence of compatriot Toby Alderweireld, Vertonghen has to take up the responsibility of leading the back line at White Hart Lane. The experienced defender has played every minute of Tottenham's Premier League campaign and has been an absolute rock at the back.

On his day, however, Alexis Sanchez is more than capable of taking on the experienced Belgian, and when they do come face to face on the pitch, a very exciting duel is in store. Alexis will have to do everything in his power to justify his status of "talisman" of the team, whereas Vertonghen will have his hands full as he attempts to contain the dynamic Chilean.
