   “The Ivorian is a player with such a liking for improvisation it does not usually look like he has any more idea than anyone else what he is going to do next, so it was an interesting choice. As it turned out, it was a masterstroke. The striker was full of running, played with a more direct shoot-on-sight approach than normal and finished with two goals and an assist.”

   “Paddington dates to 1838, although much of today's main line station is from 1854. And it is, of course, a Brunellian masterstroke.”
