Leadership
Undeniably a veteran of the game, the Swiss international has what it takes to command the respect of the younger players in the squad.
A possible steward under Emery, Lichtsteiner can bring a sense of leadership to the squad as the players will have someone to look up to. Someone who has been involved in big matches on the biggest stages in the game.
With Arsenal captain out with an Achilles injury, which sidelined him form the World Cup and the start of the campaign next season, Stephan Lichsteiner can be the calm and composed head in the relatively inexperienced Arsenal back-line with the likes of Rob Holding, Callum Chambers, and Hector Bellerin in their ranks.
Quality defensive cover
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
Experience
The biggest thing that the signing of Stephan Lictsteiner brings to Arsenal is his undeniable experience. Lichsteiner has been one of the most dependable players in his time in Italy and has also captained his national side in his 3 World Cup tournaments.
He is just one short of the magical number of 100 international caps for his side, scoring 8 goals and assisting 7 in the process.
