Innovation - look at other sports

This link here shows insights from Neville Southall, Everton's goalkeeper in the 80s and 90s. He was a well respected keeper and thought of as best in the world, for a time, in the 80s.

He talks about how he sought to improve, using alternative ideas.
For example:

• Dressing in black to make himself look larger
• Wearing the cheapest plastic boots, rather than the sponsor's top range shoes
• Getting to the ground earlier than everyone, to familiarise with the surroundings

In this account he states even a 100 changes to make a 1% improvement is worth it, at elite level.

One memorable game I can remember, is the second[half of the 1995 FA Cup final, Everton vs Man Utd.

Man U, threw everything at Southall in goal, to get back into the game and Southall did everything to stop that!
