The grudge that defined an era: Jose Mourinho’s obsession with Roman Abramovich

The partnership between Jose Mourinho and Roman Abramovich remains the most transformative period in Chelsea’s modern history. Yet, beneath the surface of six trophies in three years, a profound power struggle was brewing—one that would eventually turn a productive working relationship into a deeply personal rivalry.

A battle of wills

In a new Netflix documentary, Mourinho reflects on his 2010 return to Stamford Bridge as Inter Milan manager, framing the Champions League tie not as a contest against his former players, but as a direct confrontation with the man who dismissed him. 'Honestly, I was playing against Roman in that game,' Mourinho admits. 'I was not playing against Chelsea. I was not playing against the boys. I was playing against him.'

That game for me was beauty. I was playing against a guy that sacked me. It felt like pleasure.

The friction, according to reports from the documentary, stemmed from increasing interference in football operations. Former assistant Andre Villas-Boas noted that the relationship began to fracture over recruitment, specifically the forced signing of Andriy Shevchenko—a move Mourinho reportedly opposed in favor of Samuel Eto’o.

The 'intruders' and the power dynamic

Mourinho’s resentment extended beyond transfer policy, citing the influence of 'intruders'—agents and external figures—who he felt eroded the chemistry he had built within the squad. The manager’s frustration was compounded by the owner's demands for his time, including a request for Mourinho to assist with a recreational game on a yacht, which the manager refused.

Ultimately, Mourinho’s Inter Milan side secured victory at Stamford Bridge, a result he viewed as personal vindication. While the two would later reconcile enough for a second stint in 2013, the 2010 encounter serves as a stark reminder of the volatile nature of the Abramovich era.

• Mourinho won back-to-back Premier League titles during his initial tenure.
• The 2010 Champions League tie saw Inter Milan defeat Chelsea in both legs.
• Disagreements over the £30m signing of Andriy Shevchenko were a primary catalyst for the breakdown.
• Mourinho returned for a second spell at Chelsea in 2013 before departing in 2015.
