"Bangladesh are nothing less compared to India. Rather, we have experienced players like Masharafe (Mortaza), Shakib (Al Hasan), Mahmudullah, Mushfiqur Rahim and Tamim (Iqbal)," Islam told leading daily 'Prothom Alo'.
Islam, a right-handed batsman, played 13 Tests and 39 One-day Internationals (ODI) for Bangladesh scoring 530 and 794 runs respectively.
"Once our batting line-up does well, we can get a big score. If Bangladesh can use that effectively, victory is certain," he said.
Aminul also stressed on the fielding which he said is the key against India.
"As India's batting line-up is solid, weak fielding can be detrimental. (Virat) Kohli, Rohit (Sharma), and (Shikhar) Dhawan -- no one should be dropped if opportunity comes."
Islam tipped all-rounder Shakib to deliver in the big match.
"You should keep one thing in mind that Shakib is a big-match player."
Bangladesh defied all odds to qualify from Group A along with hosts England. They beat New Zealand in one of the greatest run-chases in Champions Trophy history after being down in the dumps at 33/4. Both Shakib and Mahmudullah scored tons and stitched together a record 224-run stand to take their team over the line.
Their progress to the last four stage was confirmed when fancied Australia, plagued by two rain-hit games, lost to England the next day on June 10.
