It is an interesting question as to how long England will continue selecting KP should his form not improve drastically. Currently, he is pushing at the ball, the bat is some distance from his body, and all these technical deficiencies in his technique unsurprisingly are exaggerated and come under greater scrutiny when he is so woefully out of nick in the middle. It is inevitable that he will go after deliveries that aren't quite there, play at balls that he should be leaving because he is searching for that moment when it clicks back to how it used to be.
If he fails in the 2nd innings at Lords, the Ashes series becomes a real battle for his place. I don't think there is any chance he won't be in the XI come Brisbane, but if after the third Test and he hasn't registered a score, I think there will be intense pressure on the selectors to make the change. I believe he'll come good by then. The KP of old lived for those situations, an Ashes series, the spotlight on him to perform, a real chance for national headlines, and generally he delivers, let's hope he still thrives in these scenarios.
The captaincy issue is a concern in that it continues to be raised, this should surely be forgotten now, and full focus should be on his batting strengths.
I'm surprised by his recent admission of being shot in the confidence department, not surprising considering his form, but it's not his way to question his own belief. There seems a lack of this hunger to become the best batsman in the world that he regularly used to say in public, that is the KP we want back. Yes he may have been ****y, perhaps arrogant, but it was nice to see an English batsman not afraid to back himself and believe he can be the best in the world.
