Trevor Bayliss has hinted England could give Keaton Jennings another opportunity to prove himself in the third Test against South Africa.
Bayliss was critical of his team after their alarming 340-run defeat against South Africa, describing the performance as a "shocker" in Joe Root's second game as Test captain.
Jennings and Gary Ballance have struggled in the opening two Tests, with Ballance now certain to miss the match at The Oval from July 27 with a fractured finger.
"One of the things we've tried to do since I've come in is try to give those guys a bit longer to show what they have got," said Bayliss.
"It still hasn't worked, to be honest. Keaton, for example, at the top of the order ... if we're consistent with our selections, he should get some more goes."
However, Bayliss did talk about potential replacements such as uncapped pair Mark Stoneman and Tom Westley as well as Haseeb Hameed.
He said: "The last selection meeting we had before this series started, players like Stoneman and Westley were spoken about at length. Obviously, (so was) Hameed - who is a little out of form this year."
"So those types of guys, they are on the edge."
England will name their squad for The Oval later this week, with all-rounder Liam Dawson's position also vulnerable.
