MOEEN Ali's England side lost the deciding match of their T20 series in the West Indies despite the Worcestershire all-rounder's inspired performance over the weekend.

Moeen smashed 63 off 28 balls and then picked up two key wickets to help England to a 34 run victory in the fourth T20I in Bridgetown on Saturday to set up Sunday's decider. 

But the tourists were unable to record a series win as they were beaten by 17 runs in a thrilling finale, in which Worcestershire Rapids captain Moeen scored 14 runs off 19 balls with the bat before returned bowling figures of 0-20 off three overs in the West Indies' innings.

Moeen, who was the stand-in captain for his country for the final two matches of the tour, said after the game that he believes these five matches have been a useful exercise for an inexperienced England side.

"I think overall it's been a great learning," he said.

"These conditions we've struggled on. We're good on flat wickets but these are the conditions we want to get better on going forward.

"Batting and bowling, they were smarter than us. I thought the West Indies were the better team, particularly (on Sunday) and overall.

"We didn't adapt well to these conditions but we played some good cricket.

"It was a great series and a great spectacle for everybody. We thoroughly enjoyed it, but we didn't win so it's a bit disappointing."
