The 29-year-old believes the wrongful award of a throw-in and the referee’s failure to act on a subsequent foul on Louis Saha ruined his side’s game plan at Eastlands
The Toffees frustrated City for almost 70 minutes until Mario Balotelli broke the deadlock from the edge of the box, and James Milner added a second for the hosts late on.
Everton boss David Moyes felt his side should have been awarded a throw-in in the build-up to Balotelli’s opener and that Louis Saha was impeded soon afterwards, and Jagielka echoed these views.
“We felt a couple of key decisions didn’t go our way,” he told reporters.
“I’ve been told it was blatantly our throw-in for their first goal, [Leighton Baines] kicked it off [Samir] Nasri and from the throw-in, they scored.
“OK, that happens. But then Louis Saha goes through and from our view, he was blatantly obstructed.
“There were a few bits and bobs like that. That obviously messed up our gameplan to restrict them and we had to change it a bit.
“When you come to City, you need that rub of the green. They have so many attacking options. If you aren’t lucky, then you aren’t going to win.”
