Sheer tenacity. Liverpool forward Luis Suarez is a terrier, running constantly in search of the ball, and his desperate will to win could push other Gunners players to up their game.
Suarez is a brilliant player with the ball at his feet, a magical dribbler able to squeeze through the tightest of gaps, and is both creator and finisher.
The Uruguayan was the second highest goalscorer in the Premier League last season, behind Robin Van Persie of Manchester United, and his record of 23 goals in 33 top flight games is a formidable one.
Of that number, Suarez scored 13 with his favoured right foot, 5 with his left, 3 headers and 2 free kicks – illustrating just what a great all round striker he is.
Capable of being both playing up front on his own, dropping deep and moving wide, Suarez finds space that few others can find, and creates it for others too.
His fitness record is also tremendous, with no absences through injury since he began playing in Europe.
Whilst Suarez’s injury avoidance is remarkable, he still misses plenty of matches through suspension.
The Uruguayan will miss the first six games of the 2013-14 Premier League season after biting Chelsea defender Branislav Ivanovic, meaning he would not make any prospective Arsenal debut until October.
That followed other bans for racial abuse, an offensive gesture towards Fulham fans, and ten yellow cards in the Premier League last season.
Suarez has not had an easy relationship with the press or fans of football in England, and a move to Arsenal may not be popular with supporters of the north London club.
Finally, if reports of the £40m release clause are accurate, he is likely to be rather more expensive than Higuain.
