Being “England’s number one” only means something if the standard is good; this is the worst era for English goalkeepers since WWII (I’d say ever but for the lack of knowledge of pre war keepers). Seaman was the last world class number one.
When you think of the players who weren’t England’s number one, the first that comes to mind being Nigel Martyn. England have been spoiled for well over half a century; Banks, Clemence, Shilton, Seaman. Tim Flowers and Martyn second and third choice behind Seaman. It’s now Pope, Foster, Pickford. Jordan had an exceptional run in the knockout games at the World Cup so he didn’t let anyone down there, but it doesn’t look like a standard he can maintain. While an excellent shot stopper his reach is an issue, plus his decision making is questionable to say the least. He always seems on edge, fidgety, which won’t transmit calmness to the defence. He doesn’t really command the penalty area either.
Having said all this, he has Michael Keane playing infront of him, a more flat footed central defender you won’t see at this level.
