There was a Liverpool Madrid match three months ago and with the centres in the Wirral, I would have expected Liverpool's figures to be higher.
The hotspots are London, Sheffield, Birmingham and Slough apparently.
I'm in Birmingham and with Crufts, Cheltenham up the road (airport serving both events) and infected Diamond passengers flying back here, we had no chance.
We are, however, the largest city outside London, so perhaps not that unsurprising.
