Spurs have scored 63, but they have conceded 61 - that isnt fixed easily without impacting the goals scored. I am sure they could become much tighter at the back, but they wont be scoring as many.

We have the 4th best defence in the league for the second season running (although I fear a last day slapping might alter that)

You are right, we need to add 15 goals whilst not conceding more, but Spurs need to concede 15 fewer whilst keeping their scoring up - not necessarily an easier task.

We need goals, and its pretty obvious which area of the pitch has let us down the most.

Our right hand side
Jack Harrison has 33 appearances 1 goal, 0 assists this season
Lindstrom was 25 apps, 0 goals, 1 assist

If we can find 4-5 goals and 4-5 assists from that position - would be a huge boost (for reference McNeil has 4 and 6 in 20 games this season)
