exertion

The latest issue has centred upon Chelsea and City, who both wanted a delayed start to the new campaign given their summer exertions.

It could be that he was simply taking care after his prior exertions in this match, and with the fifth Test at The Oval beginning on Thursday.

The exertion that was required seemed to belong to a pre-internet age.

That led to the establishment of the Clem Burke Drumming Project in 2008, whose detailed studies showed that drummers can reach the same physical exertion as professional athletes.

In the second half, Celtic's undoubted quality - and perhaps Rangers' exertions from Thursday's penalty shootout win against Fenerbahce - started to take their toll as the league leaders roared back to 2-2.
