England head into Sunday's third one-day international against Sri Lanka with coach Peter Moores impressed by the competition for places within the squad.
Moores believes Owais Shah and Graeme Swann are two players who have been forced to raise their game in order to cement spots in the starting XI.
England levelled the series at 1-1 with a 65-run victory in Dambulla on Thursday, Shah earning the man-of-the-match award for his innings of 82.
Swann, who has been preferred to Monty Panesar as England's solitary spinner in the series so far, also impressed with figures of 2-27 from 10 overs as England comfortably defended a total of 234-8 under the Dambulla floodlights.
"Owais has shown his game is suited to all conditions, he's a skilful player," said Moores. "He has also shown that he plays at his best when he plays simple shots early on.
"That's what he's starting to learn, that when he keeps hitting good areas, there's a simple run on he'll take it and he leaves his more expansive shots to be played at the end.
"Talented players know when to take simple options and he's certainly doing himself no harm. We'll see, but his emergence as a player has been interesting to watch over the last three months."
On Swann, Moores added: "He's done really well. We couldn't have asked much more of him so far. He has spun the ball and looked confident, done well with the bat - he's become a key member with his all-round contributions.
"It was a big thing to leave out Panesar and it's nothing against Monty because Monty is developing quickly as a one-day bowler.
"It's all about balance. Monty is practising and learning very quickly the art of variation and using the skills he has got as we see in Test matches and applying them in one-day cricket. You play horses for courses.
"You want it to be competitive, you want to it to be tough to leave people out, you should be having horrible conversations with captain and coaches because that means something is going right.
"Swann has come and taken the opportunity. He's got two games with three more, he's got to be able to show that he can produce, the challenges come when they get to see him a little bit.
"He's good, lots of energy, he's funny, he's a lad. You need all sorts of different people because it makes touring parties fun. In our set up the lads enjoy him."
England are likely to name an unchanged team on Sunday, meaning Panesar will again carry the drinks.
Consistency and discipline
Sri Lanka coach Trevor Bayliss is confident his side will produce an improved display on Sunday, but admits to being puzzled by the decision to schedule all five matches in the series under floodlights.
The opening three matches take place in Dambulla, before moving to Colombo for the final two games, which are both also day-nighters.
Bayliss, who is coaching Sri Lanka in his first series since succeeding fellow Australian Tom Moody, feels playing under floodlights suits England as the hot and humid conditions ease off during the evening.
"We've still got to be confident playing at home, but the one thing I've found a little bit strange coming from Australia to here was that we're actually playing five matches at night," said Bayliss.
"I can see the point of having one or two at night, but I thought that if there is a home-ground advantage, we've probably lost that by playing at night.
"I knew England would come back at some stage during the five matches - they've got too many good players not to be successful at some stage.
"From our point of view, the second game didn't go well because we didn't play as well as we could, especially in the batting - it was very poor.
"England were very disciplined in their bowling and we were quite the opposite in our batting and we'll be looking for a bit more consistency and discipline in our batting."
