Marcus Trescothick has praised Mohammad Amir

Marcus Trescothick predicts England's Test batsmen will struggle to cope with Mohammad Amir's late swing this summer.

Trescothick was dismissed by Amir for eight as Somerset slumped to 128 all out at Taunton on day two of Pakistan's first warm-up match before the opening Investec Test at Lord's, which starts on July 14.

The former England opening batsman saw enough of 24-year-old Amir to be convinced the left-armer will cause problems for Alastair Cook's side as he makes his way back after his five-year ban for spot-fixing.

Amir, in his first professional match in England since he was jailed and then suspended from all cricket for his part in the spot-fixing scam at the 2010 Lord's Test, took 3-36 against Somerset.

His wickets came at the top of the order, and all with sharp deliveries as he got the ball to swing late and at pace.

Trescothick said: "On that performance, yes he will cause problems for England. He swung the ball really late - that's the biggest thing we noticed.

"In my magnificent eight, I thought it was pretty hard work - it was tricky."

Amir still has time on his side to possibly become a modern great and Trescothick has confirmed himself as an admirer already.

"You get a lot of bowlers who swing it quite early," he added.

"But he was swinging it late - and as it was coming down the pitch, you were almost guessing whether it was an inswinger or whether it was one of the straight ones.

"Then it just sort of swings away. That's the challenge he poses."
