Jimmy Anderson is keen to retain his competitive edge after England endured a frustrating day at Edgbaston which saw Pakistan trail by just 40 runs with seven wickets in hand by the end of play.
Anderson was warned twice about running on the wicket by Bruce Oxenford as the tourists closed on 257-3, thanks to Chris Woakes removing Azhar Ali for 139 with the final ball of the day.
The leader of England's attack said he had apologised to both umpires and labelled a day in which the home side took only three wickets as "very frustrating".
He explained: "I’ve always had a bit of an issue with running on the wicket, I know I’m tight. I probably got a little bit out of order at one point with the umpires - I’ve apologised to both of them for my behaviour but that’s just the way I play the game.
"I’m competitive, I want to try and get wickets and when the day is like that it can get a little bit frustrating. I’d rather have that competitiveness, it has helped me in the past, but obviously I want to play within the spirit of the game.
"You’re trying to do everything possible to get your team back into the game and distractions like running on the wicket don’t help."
Anderson said England would be boosted by the dismissal of Azhar with the last ball of the day: "It was a great wicket. I thought all five bowlers put in a really good effort. We kept at it, they played well and it's nice to get that breakthrough at the end of the day - there’s a few more smiles in the dressing room.
"Obviously, with us not making 300 in the first innings we knew we had to make breakthroughs which we didn’t quite do. The pitch seemed to be a bit slower than yesterday. You felt in the game, it carried quite well but seemed to have lost yesterday’s zip.
"I thought we bowled pretty well, we kept them under three an over for most of the day, a couple of chances went down which is frustrating. You get days like this in Test cricket and all credit to those two guys, they played really well."
