Why captain Buttler 'didn't enjoy' England's win vs SL

England qualified for the Twenty20 World Cup semi-finals with a nervy victory over Sri Lanka by four wickets in their final Super 12 match on Saturday, sending hosts and defending champions Australia out of the tournament in the process.

Superb death bowling from Mark Wood (3/26) and Sam Curran restricted Sri Lanka to 141/8 and although they made heavy work of it, England reached their target with two balls to spare when Chris Woakes cracked a four through backward point.

The 2010 champions claimed a spot in the last four along with Group 1 winners New Zealand and on Thursday, will play the runners-up from Group 2, who will be decided in Adelaide, on Sunday.

"I'm not a great watcher and I didn't enjoy that at all. We know we had to find a way to win it and thankfully we did. We get through to a semi-final which is really exciting," England captain Jos Buttler said of the tense finish.

Australia had needed a Sri Lanka upset to keep alive their chance of progressing but those hopes looked to have been dashed when Pathum Nissanka was dismissed for 67 in the 16th over of the Asia Cup champions' innings.

Nissanka clubbed Ben Stokes for the first of his five sixes from the second ball of the innings and by the end of the 15th over Sri Lanka were 116 for three and looking good for a decent score at a ground where chasing can be hard.

Spinner Adil Rashid had Nissanka caught at the long-on boundary by substitute fielder Chris Jordan to take his first wicket of the tournament and Sri Lanka fell apart, scoring 25 for five over the last five overs.

Openers Alex Hales and Buttler put on 75 for the first wicket before the England skipper was dismissed for 28 by Chamika Karunaratne's fine diving catch at deep midwicket, off the bowling of Wanindu Hasaranga.

Hasaranga removed Hales, caught and bowled for 47 soon afterwards before Harry Brook, Liam Livingstone and Moeen Ali followed cheaply to leave England wobbling on 111-5 in the 15th over.

The victory target was never much more than a run a ball away, however, and Stokes (42 not out) and Woakes (five not out) got them across the line in the final over on 144 for six.

"It was an amazing fight but we could have done better in the batting part. We played good cricket in patches (over the tournament) but we had a lot of injuries," said Sri Lanka captain Dasun Shanaka.
