Next season I'd be playing Clyne in all European games and all Premier League games against what we perceive to be top 10 - 8 opposition. He's proven himself to be a solid, dependable consist defender who can offer a threat in attack, especially with space for him to move into.
For the other fixtures, against the dross, where we know we're going to dominate the ball and spend a lot of time in possession in their half, I'd be playing Trent who seems a lot more comfortable on the ball, seems to be a better dribbler and has a hell of a cross on him. Possibly even Milner can get game time here if we've brought in another left back or Moreno has developed a brain and positional awareness.
By doing this, we save ourselves what, the £20 million quid? it takes to improve on Clyne and are able to spend that on the other areas that clearly need improvement in the starting 11.
