I honestly like Lindelof's style of play, yes he's a bit rough around the edges but hes only young, I think if he and Bailly can get some consistent game time together with Tony at RB as an experienced head at the back (I'm hoping we sign a new left back) then I think we could be looking at a seriously strong centre back partnership.
Look back on United centre back partnerships of old:
Bruce and Palister (if this is wrong don't judge me I'm only 19)
Rio and Vidic
Two world class centre halves, one always a ball playing centre half and one 'hard man', now we decide to play Smalling and jones, we might as well start Laurel and Hardy at the back, yes they're alright as backups but to start Premier League and Champions league games is ridiculous.
Give it 2 seasons and Lindelof and Bailly will be 2 of the best centre backs in the world, that's if Jose lets them work together
