Reina was a doubt for the opening game against the Gunners as he hasn't played a single minute of pre-season because of his late return to Melwood following Spain's World Cup win and this week he pulled out of Spain's friendly against Mexico with a shoulder injury.
However, the injury has been shrugged off and Reina will start as Roy Hodgson is set to name the strongest side available against Arsenal. This could also include Javier Mascherano as nobody has yet met the Reds' £25m valuation of the midfielder.
