Fortune again failed to favour Clarke and his team when referee Michael Oliver awarded Ipswich a penalty only for VAR take it away. Oliver ruled that McNeil had again kicked Clarke but a look in the monitor indicated the opposite was actually true.
McKenna infuriated by VAR interferenceMcKenna remained unconvinced however. "I find it inexplicable," he said. "McNeil lunges across the line of the ball. He made no attempt to play the ball, and he stopped Jack taking his shot.
"I can't understand how all the directives we have had say that unless it is a clear and obvious error, then it won't be reviewed and the referee's decision on the field will stand."
Ipswich confidence was eroded further by an Everton second five minutes before the break. Cameron Burgess, on his Premier League debut, needlessly conceded a corner that was just about cleared out of the box - but Keane was quickly located in space on the left of the area and the centre-half produced a finish to match Ndiaye's.
The second half was less memorable, with the hosts only looking like they might make a comeback once McKenna began sending on fresh legs.
Jordan Pickford was required to make saves from Omari Hutchinson, Conor Chaplin and Jack Taylor, with Calvert-Lewin again denied by Muric.
Keane answering his criticsKeane, last capped by England in 2020, was the big winner on a day when Everton moved four points away from a cluster of clubs on four points that includes Ipswich.
The centre-back, 31, was a Dyche stalwart at Burnley and a regular pick for the Toffees for five seasons. The emergence of Jarrad Branthwaite, deemed not quite fit enough to make a comeback from injury in this one, has seen him eclipsed in recent months.
"Keano has had a lot of question marks over him - and haven't we all, by the way?" said Dyche. "I thought he delivered a very good performance with a very good goal - he is an excellent finisher.
"Of course I was loyal to the ones who played last season because they were excellent. He is earning the right to play and that is all you can ask of players."
