Early wickets, fluffed chances, a bumped catch claimed, plenty of referrals and a maiden Test century made for an interesting opening day of the series at Trent Bridge as England finished on 331 for four.

Pakistan had the early advantage, but Eoin Morgan's fine unbeaten hundred and 81 not out from Paul Collingwood steered England out of trouble.

Facing the swing bowlers under cloudy skies was always going to be tricky, just ask Australia's batsmen. But Andrew Strauss had no hesitation in making first use of a dry-looking pitch when he won the toss. His counterpart Salman Butt admitted he would've batted first as well.

Strauss was lucky not to make his way back to the dressing room five overs into the match as Mohammad Aamer's brilliant delivery went unrewarded due to some shoddy glovework from Kamran Akmal. Aamer caught the edge after getting one to seam away from the left-hander only for the wicketkeeper to make a meal of the simplest of catches.

Four overs later and Alastair Cook wasn't as lucky as Aamer got his just deserts when the opener edged it to slip. Jonathan Trott and Strauss were allowed to score pretty freely before things got interesting again with the third umpire having plenty of work to do.

Trott was given his marching orders by umpire Asoka de Silva, but the No 3 confidently referred it and he was vindicated when replays showed he got a big inside edge onto his pads. Pakistan though did get another wicket before the break, and Aamer was again the man to do the damage as his extra bounce caused Strauss to nick one to the keeper. No mistakes from Akmal this time as the skipper departed five short of his half-century.

Pakistan's bowlers continued where they left off before the break with three decisions referred upstairs in the space of 10 overs. The visitors twice thought they had dismissed Kevin Pietersen only for the TV replays to prove umpire de Silva right on both occasions. First they referred an lbw decision that was given not out and then they were convinced Pietersen had nicked one through to the keeper only for the replay to show the noise came from bat hitting pad.

They finally got a breakthrough in the 33rd over with Pietersen's scratchy innings coming to an end as his inside edge flew onto his stumps from Mohammad Asif. Trott was on his way an over later and not even the third umpire could save him as Aamer trapped him lbw as he shouldered arms. He referred it, but it ticked all the right boxes and England were wobbling at 118 for four.

But up stepped Collingwood and Morgan to put England back on track. You'll find it difficult to find a more effective combination than these two - one likes to counter-attack while the other is known for digging in when the going gets tough.

Morgan, who had a bit of a scare on five when keeper Akmal claimed a bumped catch only for the TV umpire to show it touched the ground, really took the fight to Pakistan and he reached his first Test half-century in no time. His partner took a bit longer, but he eventually got to that milestone and they shared an unbeaten 213-run stand which is the best fifth-wicket partnership for England against Pakistan.

Morgan had the decision review system to thank again, when on 78 umpire de Silva gave him out lbw off Kaneria, but it was missing leg stump. His partner was also given an extra life when Akmal missed an easy stumping chance with Collingwood on 48.

The left-handed Morgan motored through the 80s and 90s to reach three figures in Test cricket for the first time. He did it in style, going straight down the ground with a six.

Pakistan's bowlers really lost their way in the final session and the classy Aamer (3 for 32) had no support from the rest of the attack, with Danish Kaneria particularly poor. Kaneria though will complain he had no help from the fielders who fumbled their way through the day.

Shot of the Day
Eoin Morgan coming down the track to Danish Kaneria and hitting with the spin over the head of mid-off.

Delivery of the Day
Superb seam position from Aamer and the ball squares up opener Cook. The left-hander has to play at it and he edges it to Imran Farhat at first slip.

Moment of the Day
Morgan again. This time he puts his dancing shoes on for Shoaib Malik and goes straight down the ground to bring up his maiden Test century with a six. Is there a more glorious sight in cricket than seeing someone celebrate three figures for the first time?
