Even though it stings to lose out on such an obvious improvement to our squad and to our right back play, I think there are still options out there that we can get in the summer that wouldn't cost an arm and a leg and would still improve us. Frimpong at Leverkusen and the two RBs at Southampton (Livramento and KWP), especially if Southampton go down, are names that come to mind.
But we need to be very clear-eyed in the summer and act fast. As soon as the season ends priority should be to offload all our deadwood that can fetch us some money (Maguire, AWB and Mctominay in particular) at all costs and immediately start working on signing improvements.
