Sir Alex Ferguson coined the phrase 'squeaky-bum time' 20 years ago, as April loomed. April is the acid test for a manager and Erik ten Hag's results are mixed.
Ten Hag's in-game changes have been one of United's biggest strengths this season but this month they have been one of their biggest weaknesses. They have contributed to negative results in three matches in April alone.
There was muddled thinking at Newcastle, United's capitulation against Sevilla started with the frivolous changes on the hour of the first leg and United were weakened with each batch of double-changes at Tottenham.
