It certainly was not all plain sailing. There have always been suspicions that he was not quite committed to the cause. Some of that is perhaps a legacy of the fact he represented the England youth sides, and so came to be viewed, when he did opt for Nigeria, as a reject of the English national team. It is a legacy of the paradoxical mix of pride and self-loathing that encapsulates the Nigerian psyche.
Spurious (or otherwise) as that impression was or may have been, his body language and temperament certainly didn't help. Whereas a player like Alex Iwobi, who similarly opted for Nigeria following a period in the English youth system, is extroverted (in keeping with the jocular persona of the average Nigerian) and seems eager to connect socially, Moses' aloofness and ubiquitous sneer seemed to evince paranoia and mistrust.
These human factors make his legacy somewhat hard to pin down, but purely on a numbers level, it is hard to knock his contribution when he was available.
His decision to focus on his club career and young family is understandable, although one is tempted to be churlish and point out he is unlikely to feature heavily under Blues boss Maurizio Sarri, a manager whose track record with rotation is not excellent. If not having to jet out of London to play Seychelles and Libya is what facilitates that, then he has earned the right to put his feet up.
One might even say he retired at precisely the right time. This is because, and whisper it quietly, Moses had begun to hold the Super Eagles back. And it would only get worse if he had stayed on.
It is profoundly ironic that the very move that resurrected his club career at Chelsea effectively killed his international career. The longer he played wing-back under Antonio Conte at Stamford Bridge, the harder it became to maintain his level of performance as a forward with the national team.
What made the dissociation even more violent was the fact that, under the former Chelsea boss, Chelsea often played on the back foot and sought to spring forward quickly. This meant that, even though the wing-back role requires attacking verve, Moses spent a great deal of time minding his defensive duties.
Things came to a head at the World Cup where, after a limp opening loss to Croatia, Super Eagles coach Gernot Rohr decided to switch to a system with wing-backs. It was clear there and then that, within a system that the 27-year-old was not even the best wing-back in the squad.
