Mauricio Pochettino's muddled tactics could genuinely cost him his job at Chelsea - he must play to his and the Blues' strengths

Just seven games into his tenure as Chelsea manager, it's clear that the job at hand is already weighing heavily on Mauricio Pochettino. The picture of cool, calm and collected when he was presented as the Blues' new head coach back in July, the Argentine looked bemused and beleaguered as his side went down to Aston Villa on Sunday, the Blues' second successive home defeat.

He is, of course, contending with significant extenuating circumstances, with almost half of the first-team players that he was hoping to call upon this season already out injured for varying lengths of time.

However, Chelsea's stuttering start has regardless failed to inspire confidence that the Blues' fortunes are going to change quickly. It is Pochettino's job to guide them through the storm, but at present it is uncertain that he is following the correct course.
