Only Arsenal have more goals and assists from substitutes this season. I appreciate that's not the full picture but shows that his subs make an impact.

I also think part of the not changing system is to ensure we learn it. You can't learn if you ditch the approach at the first sign of trouble.

If you look at Napoli they got incrementally better season after season.

There is no doubt we need new players as well. A striker that can score goals on a regular basis would be a great start!
