Just as England can now expect to face a spinner at the start of all their World Cup innings, they will also have to cope with opponents trying extra hard to wind them up.
A far bigger concern for the hot favourites than defeat at the hands of Pakistan on Monday was the way England lost their cool in the face of relatively mild provocation, which will surely be ramped up for the rest of the tournament.
The fines the ICC handed out on Tuesday to Jason Roy and Jofra Archer after the thrilling, fractious 14-run defeat at Trent Bridge were symbolic of a worrying lack of discipline in the field from a usually relaxed and fearless England.

Now they will not only have to beat Bangladesh in a massive game at Cardiff on Saturday, but also prove they are not affected by the pressure and expectations that came with their spectacular rise to the top of the 50-over world.
After his outstanding start to the tournament against South Africa, Roy in particular appeared to feel the heat in Nottingham.
His error-riddled display was so hot-headed that captain Eoin Morgan at one stage banished him from cover point.
In truth, a fine of 15 per cent of Roy's match fee, for breaching level one of the ICC code of conduct, is an overly officious punishment from a governing body that specialises in pedantry, rather than tackling the game's biggest issues.
Roy may well have been guilty of mouthing an 'audible obscenity' after a misfield, but really, is that such a big deal?
It is highly unlikely any spectator in a heaving Trent Bridge would have heard him - let alone been offended by what he said - so unless umpires Marais Erasmus and S Ravi are more delicate than imagined and took issue, it seems heavy-handed.
The same punishment for Archer, for dissent towards an umpire for signalling a wide, was more justified. It was also a reminder of the inexperience of a rare talent who will suffer bad days like this, as well as plenty of good ones.

It could have been worse and England should be relieved it was Pakistan captain Sarfaraz Ahmed who was fined for a poor over-rate rather than Morgan, after the hosts took 19 minutes longer than allotted to bowl
