The Red Devils veteran has backed The Special One to deliver at Spurs but concedes his first match was far too easy
Roy Keane has backed Jose Mourinho to succeed at Tottenham but stressed his first game in charge was straight forward courtesy of a West Ham side he described as an "absolute disgrace".
After parting ways with Mauricio Pochettino on Tuesday before appointing Mourinho less than a day later, Spurs began life under their new manager with a bang.
Tottenham struck three times after just 50 minutes on Saturday before conceding twice late on as they had to settle for a 3-2 win.
