The bowling coach believes the same is true of Finn, while Panesar appeared to be hampered as much as anyone by the slow pitch.
"I think Monty at times has looked really dangerous, over the wicket, and around," said Saker.
"It's not one of those wickets that really zips and turns that he was used to in India. He just hasn't had that zip he might have wished for."
The one wicket England managed on day four was Peter Fulton's.
The stubborn opener still cited Anderson as England's best bowler, but said: "It looked like he was struggling with something maybe ... I'm not sure whether it was injury or the footholds.
"But as we found out in Dunedin, when you spend a lot of time out there, it obviously takes its toll (on the bowlers)."
"There's some turn there for Panesar. But for the seamers, especially with the older ball, it's pretty placid."
