Indeed, the former West Ham midfielder responded to a tweet suggesting the 24-year-old Chelsea winger had turned Spurs down with glee.
Sinclair feels it is a sign of Moses winning over the Hammers faithful and was excited by the fact the Nigerian wasn't interested in a move to Tottenham.

Of course, it's unclear whether that was actually the case, with Moses linked with West Ham for several days heading into Deadline Day.
But Tottenham have been recruiting wingers all August and the Daily Mail reported last night that the north London side were indeed looking to hijack West Ham's bid for the Chelsea winger.
Should details emerge that the 24-year-old did indeed turn Spurs down, the Hammers faithful will no doubt be over the moon.
Moses' first-team chances appear far greater at West Ham than they would have done at Tottenham. But have the north London side missed out on a top player or will Moses' spell at Upton Park be closer to his time at Liverpool than Stoke?
