3 things Lichtsteiner brings to Arsenal

#2 Quality defensive cover

Hector Bellerin has been caught-out way too many times this season.

Arsenal have never had one of the most defensively sound units, at least not since 'The Invincibles'. What they have lacked even more is the quality in depth that the substitutes playing for a club with a stature of the North London side should possess. Or simply, have lacked any depth at all.

After losing Bacary Sagna to Manchester City, Wenger got extremely lucky when Hector Bellerin more than just stepped up to the occasion. In fact, he went on to make the spot his. The former manager decided to bring in a Mattieu Debuchy to provide cover for the Spaniard but his association with long-term injuries did little to help the cause.

In Stephan Lichsteiner Arsenal finally, have a defender who not only is decidedly top quality but also possesses the astute defensive mind of an old-fashioned defender, in sharp contrast to the attacking mindset of the modern day wing-backs. Something which has cost Arsenal dearly, even recently with Bellerin when he looked completely out of his depth when asked to perform his defensive side of duties, over the course of the season.

The Swiss international can also slot into the centre-back position with Koscielny when he is eventually back alongside either Monreal of Mustafi. That looks like a much more assured back-line that the one which failed to keep a clean sheet away from home in all but one game since the turn of the year.
