6) Tottenham Hotspur: Right-Back
Mauricio Pochettino has managed to build a squad that is actually capable of winning the Premier League title but is yet to show that consistency over a full season. There is no doubt that Spurs have been the best side over the past two seasons combined but have always fallen in the final stretch.
Surprisingly, Spurs have managed to keep their entire core intact and are yet to open their purse strings in the transfer market as they move to Wembley Stadium this season while White Hart Lane is rebuilt. They don't have happy memories of Wembley and their home form will be looked at with a magnifying glass this season - especially after they never lost at home in 2016/17.
But Kyle Walker's fallout with Pochettino and eventual sale will see Spurs short at the back. While Kieran Trippier is an able replacement - a player Pochettino preferred to use instead of Walker - there is no backup option should the 26-year-old be rested (or worse - gets injured).
Even if Pochettino plays a back-three, Trippier will be used as a right midfielder or wing-back - just as Walker was when he was played.
Spurs are also in Europe this season but whether Pochettino will focus on that or not is another matter. However, going into the season with just one decent right-back would be a grave mistake.
