Why were the top teams so rusty?

If you only had one word to sum up the performances of the Premier League’s biggest clubs on the first weekend of a new season then ‘rusty’ would be the most likely choice.

So what does that say about the way teams are preparing in an era when every medical and scientific advantage is available to them?

Arsenal’s display was perhaps the worst; so many missed passes, poor decisions and even a lack of energy in the final 15 minutes against West Ham, just when you expected a traditional late bombardment at the Emirates.
