England all-rounder Moeen Ali attributed his recent slump to external criticism, which he has resolved to ignore from now on after a spectacular return to form in the final Twenty20 international against Pakistan.

Moeen had made just 10 runs in his previous four international innings this summer but a sensational 61 from 33 balls – featuring four fours and as many sixes – helped England recover from 69 for four in their pursuit of 191.

While Pakistan ultimately prevailed by five runs in a last-ball thriller at Emirates Old Trafford to square an entertaining series at 1-1, Moeen was relieved he was able to make a positive contribution.

Asked if there were any factors behind his low run of scores, Moeen said: "The outside noise more than anything, you can get sucked into that.

Pakistan finished their tour with a win, having been beaten 1-0 in Tests, while they ended England's hopes of a sixth successive T20 series victory ahead of their limited-overs series against Australia, which starts on Friday.

Mohammad Hafeez top-scored in Pakistan's 190 for four with 86 not out, while teenage debutant Haider Ali showed why he is one of his country's hottest prospects with some formidable strokes in his 54 from only 33 balls.

Haider, 19, showed a penchant for the leg-side in his 100-run stand with veteran Hafeez, who hailed a team-mate 20 years his junior.

Hafeez told Sky Sports: "He was good under pressure and just expressed himself. It is great to see youngsters coming from our system and performing well."
