England captain Joe Root has been impressed by the maturity shown by under-fire opener Keaton Jennings ahead of the fourth Test against South Africa at Old Trafford.
Jennings' place is under scrutiny following a difficult series, although he seems to have earned a stay of execution with a 48 in the second innings of England's 239-run win at The Oval.
Root hinted he would retain his place tomorrow as the skipper revealed his admiration for how Jennings, who has played only five Tests, goes about his business. Root said: "He's a very level-headed guy, he's got a very strong character and throughout he's been much the same in the way he's approached his training and in each game as well.
"It's great to see someone so light of experience be very mature and go about it the right way.
"The way he played in that second innings was extremely great to see, hopefully that'll lead into some more runs."
Jennings made a century in his debut Test innings in India last winter but is averaging only 15.33 after three matches against South Africa, with his technique criticised by some.
And Root acknowledged it is increasingly difficult to become established in Test cricket. He added: "It's tough, and that's why it's called Test cricket, it can be a very hard thing to break into.
"You come from county cricket where there's not a huge amount of exposure to the media and external scrutiny - and you have to get your head around it pretty quickly. It is a test of character and skill."
Heavy rain in Manchester has hampered preparations for the final Test, into which England take a 2-1 lead, with heat lamps being used to keep the pitch dry.
A passing shower yesterday morning left the outfield waterlogged although Root insists it is not a concern for his side as he looks to wrap up victory in his first series leading England.
He said: "All we need to focus on is making sure we look to win this game.
"It (the wicket) was under-prepared and a lot can change in 24 hours, so we'll make a judgment on the side tomorrow."
