England captain Alastair Cook blamed “naive” batting for the 75-run defeat in the first Test against Pakistan.
Leg-spinner Yasir Shah’s figures of 10-141 helped bowl England out for 272 and and then 207 at Lord’s.
The 283-run chase ended with Mohammad Amir , on Test return after a spot-fixing ban, taking the final wicket.
Cook said England lost the game in the first two days, adding his batsmen “were getting confused with different angles which you don’t always get”.
Cook said: “Chasing 280 you need someone to play out of their skin, get a hundred and for people to bat around him.
“We allowed Yasir to get six wickets when he wasn’t turning the ball. It cost us. We needed to go past him in the first innings to have a chance.”
Yasir’s haul was the best by a Pakistani bowler at Lord’s, though for a while on Sunday England looked capable of pulling off what would have been their second-highest successful run chase at this venue.
“It was a great day’s cricket,” Cook said. “It’s been a really good Test. It ebbed and flowed. Neither side grabbed the initiative. Pakistan always had their noses ahead.
“As always when you lose you look at things to improve. What we’ve seen shows it’ll be an exciting series.”
A 56-run stand for the seventh wicket by Jonny Bairstow (48) and Chris Woakes (23) had kept the Lord’s crowd in good spirits after Gary Ballance and James Vince had contributed 43 and 42 respectively.
Rahat Ali’s three morning wickets had caused major damage, though, while Yasir removed Ballance, Moeen Ali, Bairstow and Woakes to leave Amir the job of cleaning up Jake Ball’s stumps.
England have won just one of their last six Tests at Lord’s – against New Zealand in May last year – with two draws and three defeats.
Defeats include those by India and Australia, the latter a 405-run loss during coach Trevor Bayliss’ first series in charge.
“We’re playing on our own turf, we’ve got to play and defend like it is our home turf,” Bayliss said.
“I don’t think we started very well. I didn’t think our fielding was anywhere up to scratch. That set the tone for the rest of the game.”
Cook, who scored 81 in the first innings and eight in the second, added: “It hurts, you never like losing at Lord’s at any stage. We will need time to regroup.
“We’ve lost here before, Australia thrashed us here, but we bounced back.”
