There's is plenty of other top-drawer talent available. Here's a brief look at 10 of them:
Mahela Jayawardene: He may be getting on a little but the 36-year-old is still one of the world's top batsman as evidenced by his 89 off 51 balls recently against England.
Daniel Vettori: Injuries have impacted the Kiwi all-rounder's contributions of late but anyone who boasts a 6.36 economy rate from 111 matches of bowling is a valuable T20 addition.
Shakib Al Hasan: Arguably Bangladesh's finest ever player, the all-rounder can win games with both bat and ball and has plenty of worldwide experience.
Shaun Tait: Don't expect much finesse from the Australian right-armer whose game is based purely around bowling fast. And 157 wickets from 118 innings of T20 bowling is evidence of his success.
Umar Akmal: The talented Pakistani batsman has had a topsy-turvy career but, as per his recent 94 off just 54 balls against Australia, the 23-year-old can play.
David Hussey: With over 5,500 runs, Hussey is currently the third-highest run-scorer in T20 history. The Victorian is capable of playing a wide range of innings and adds experience to any middle-order.
Junaid Khan: Left-arm paceman Junaid Khan's reputation continues to grow and his variation and control makes him a useful addition to any bowling attack.
Jesse Ryder: The bludgeoning Black Caps opening batsman scores runs at a ferocious pace with a game tailor-made to the demands of T20 cricket.
Vernon Philander: Arguably more suited to the longer forms of the game, the South African seamer still brings big game pedigree to the table and is no mug with the bat either.
Tillekaratne Dilshan: So good he's got his own personalised shot, Dilshan's returns have waned a little of late but he's still capable of getting an innings off to a flier.
