Eoin Morgan has been told he must examine his distinctive technique before winning a recall to England's Test side.
The Dubliner was left out of a 16-man squad for the two-Test series in Sri Lanka next month, paying the price for his struggles against Pakistan in the United Arab Emirates.
And England team director Andy Flower said: "I think he has got some work to do on his Test game and that's going to be quite difficult for him considering his next cricket is going to be IPL cricket."
Morgan looked far from his best in all three formats - his unique crouch at the crease becoming more exaggerated and less effective as the trip progressed - but he has enough credit in the bank to be sure of his place in the limited-overs side for some time to come.
That cannot be said of the longer form, where his meagre return of 82 runs in six innings merely added fuel to the theory that his game is not yet entirely tailored for Test success.
Morgan came into the series with a reputation for being an inventive and positive player of spin, but leaves having been dominated by Pakistan's slow bowlers Saeed Ajmal and Abdur Rehman.
Now Flower has warned him he must take a serious look at his game if he is to earn another chance.
"When he comes back (from the IPL) he'll have limited exposure to opportunities to get four-day cricket under his belt so he has got to go away and give some serious thought to his method in Test cricket," said Flower.
"He's had a tough tour of the UAE, we've been here for two months and it's been hard work for him.
"He has been severely tested out there by the Pakistan spinners, as have all our batsmen."
