Marcus Trescothick hailed the performance of Mohammad Amir after the Pakistan seamer made a notable impact on his return to action on English soil.
Left-armer Amir was banned from international cricket for five years following his involvement in the spot-fixing scandal that overshadowed Pakistan's last tour of England in 2010.
The 24-year-old will return to Lord's, the scene of his crime, next week for the first of four Tests and looked in fine form as he returned 3-36 on day two of his country's tour match with Somerset at Taunton.
Former England batsman Trescothick, one of Amir's scalps on a dominant day for Pakistan, said: "I was impressed. I didn't face him very long before he got me out, but the three wickets he got were very good deliveries.
"He swung the ball so late, that was the thing that we noticed more than anything else. It was almost like the ball was angling in and then it would swing away and obviously for left-handers, that's pretty tricky. It was pretty hard work.
"What's done is done. He came out and bowled fantastically well. If he continues to bowl in that fashion during the [Test] series ahead then it will make for good viewing."
Pakistan opener Shan Masood said of Amir: "He hasn't lost it, if anything he's only got better. We have no doubts about his talent. We've seen it before and we're seeing it again."
Sohail Khan also claimed three wickets for Pakistan as Somerset slumped to 128 all out on Monday in reply to the tourists' 359-8 declared, which featured 104 from Younis Khan.
Pakistan went on to reach 140-4 in their second innings for a lead of 371, Azhar Ali contributing 50 not out.
