What we need is another option at left-back, but not necessarily someone who is going to play every league game. We need someone who is tall enough to deal with the aerial threat and physically up to the challenge of playing against certain sides, but at the same time is comfortable enough on the ball to play the inverted role or do some attacking in the final third. Ake can handle the defensive duties but just isn’t comfortable enough on the ball in attack. Further, as we’ve seen this season, we can’t always rely on our centrebacks fit, so we definitely need someone.
