Jennings is a good player of spin - 100 on debut in India wasn't it? I would be astonished if he doesn't open the first test in SL so for that reason I'd keep him in for the Oval.
For years in the Championship they were utter garbage and never sold out. All of sudden they magically sell out and get a bit noisy. Diabolical set of fans.
He was head and shoulders the best player in the Championship when he was at Blackpool, and defintely the best player I saw us up against that era. He will do very good job in the Championship I'd wager.
The majority of MUSCULAR injuries these days are down to archaic training methods and lack of rest time. I would put the ball firmly in Hodgson's court for that.
