The South African born wicket-keeper was a controversial inclusion in the ODI squad for the series in Bangladesh earlier this year before starring in the World T20 victory in the Caribbean.
But the hard hitting opener has looked drastically out of nick during his recent efforts, scoring just 121 runs in eight innings against Australia and Bangladesh.
And Flower, who has regular test wicket keeper Matt Prior waiting in the wings, admitted the Somerset man had work to do in order to cement his place.
Ã¢â‚¬Å“Craig has had an interesting time of it recently,Ã¢â‚¬Â said the former Zimbabwean captain.
Ã¢â‚¬Å“He’s gone from scoring a hundred in his third ODI, to getting the Man of the Match award in the Twenty20 World Cup final, and being a World Cup winner, when a lot of English players haven’t.
Ã¢â‚¬Å“So he’s up there doing that and achieving that, and then he’s had a bit of a hard one-day series.
Ã¢â‚¬Å“But international cricket can do that to you. It can teach you some lessons and perhaps expose a few doubts.Ã¢â‚¬Â
Kieswetter is just 22 and many pundits see his potentially superior batting prowess, which could see him bat at six in test cricket, as a key ingredient in EnglandÃ¢â‚¬â„¢s future plans.
But rather than putting pressure on PriorÃ¢â‚¬â„¢s test place, Kieswetter could be struggling to hold down his one day slot.
Ã¢â‚¬Å“I think in the long run for Craig it might be a very healthy thing to have happened, in that by the time he plays for England again, he’ll need to have made his package stronger,Ã¢â‚¬Â Flower added.
Ã¢â‚¬Å“There are a number of things he can learn from the last nine one-day internationals, and it is his job and responsibility to go away, work hard with Somerset and come back a stronger package.Ã¢â‚¬Â
