I am not convinced that our defence is as bad as being made out on this forum.
Looking at last season, 7 teams shipped more goals than we did - Everton (58 - 8th), Leicester (59 -9th), Bournemouth (61 – 12th), West Ham (68 - 13th), Watford (64 – 14th), Huddersfield (58 – 16th), and Stoke (68 – 19th). Swansea (18th) and West Brom (20th) conceded the same number as us – 56. Arsenal (51 – 6th), Palace (55 – 11th) and Brighton (54 – 15th) also let in over 50 goals.
That places us in joint 11th for the most goals against. If you look take our worst five matches (Liverpool 0-3), Leicester (1-4) Spurs (2-5), Newcastle (0-3) and West Ham (0-3) then 18 (32%) of the goals conceded in the season came from just 5 (15%) of the 38 games played. The average conceded in the 33 other matches is just 1.15 goals per game. Only Man City, Man U, Spurs, Liverpool, Chelsea and Burnley bettered that adjusted rate over the season.
To my mind we have some young defenders that now have some proper PL experience, and will no doubt further improve under Sparky, I can’t see why a major overhaul is needed for in the defence.
The real problem lies at the other end of the park. Only Brighton (34), Huddersfield (28), Swansea (28), Stoke (35) and West Brom (31) scored fewer than Saints’ 37, placing us in 15th position. If 5 of the 15 drawn matches had been converted to wins (including Leicester) then we would have finished 9th, if we had also managed to beat Everton the we could have ended up in 8th place.
