Peter Moores admits Jos Buttler has done himself no harm in pushing his name forward for an England Test call-up, although Matt Prior will be a strong contender if he is fit.
Wicketkeeper-batsman Buttler smashed an impressive 121 from just 74 balls as England fell seven runs short in their fourth one-day international against Sri Lanka at Lord's on Saturday.
The two teams are set to battle out the fifth and final ODI at Edgbaston on Tuesday before England then announce two days later their squad for the first Test between the sides, which starts on June 12 at Lord's.
With Prior short of form and fitness following an Achilles injury, coach Moores and skipper Alastair Cook must decide whether the time is right to call up Buttler for his Test debut.
Moores, who has a fully fit squad to choose from for Edgbaston, told Sky Sports: "Well obviously Jos has been talked about a lot.
"I mean certainly, how he played the other day doesn't do him any harm, it was a fantastic innings.
"And I think Jos is a rapidly-emerging player so he's certainly, as I say, done himself no harm."
Moores added Prior's fitness is something the selectors are monitoring and they know more on a daily basis.
"I think if he's fit then he's a very strong contender. But, as I say, Jos for me is improving quickly. I thought he kept really well as well, so certainly (he's) pushed his name forward."
While Buttler himself does not think he is ready for Test cricket, Moores was quick to note that not everybody is totally prepared when the opportunity comes along.
"So Jos quite rightly would say listen 'I'm not quite the finished article' and he wouldn't be, not many people are," Moores continued.
"The key is whether that's the right time to introduce him to Test match cricket or not.
"That's a decision that's got to be made between myself, other selectors and obviously Cookie will have a strong influence."
Asked if Chris Jordan had played himself into consideration for the two-match Test series after taking 11 wickets in the ODIs, with best figures of 5-29, Moores replied: "Well obviously we've got a debate to talk about that.
"Again he's another guy that's had a good series, bowled well, bowled in consistent areas and looks like he really revels in the environment of international cricket which is great.
"So that obviously puts him again in the frame."
