php-http/client-implementation ^1.0 -> no matching package found

>composer require sparkpost/sparkpost
Using version ^2.1 for sparkpost/sparkpost
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

 Problem 1
 - Installation request for sparkpost/sparkpost ^2.1 -> satisfiable by sparkpost/sparkpost[2.1.0].
 - sparkpost/sparkpost 2.1.0 requires php-http/client-implementation ^1.0 -> no matching package found.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
 see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

Solution :
You need to install both guzzlehttp/guzzle and php-http/guzzle6-adapter

$> composer require guzzlehttp/guzzle

$> composer require php-http/guzzle6-adapter

then retry

$> composer require sparkpost/sparkpost
