Everton boss Carlo Ancelotti pinpointed one particular aspect of football his side have worked especially hard on, while Dominic Calvert-Lewin revealed the Arsenal weakness they exploited.
Everton moved up to second in the Premier League table to keep fans dreaming of Champions League qualification.
An own goal from Rob Holding opened the scoring before a Nicolas Pepe penalty pegged the hosts back.
But from a set piece, Yerry Mina nodded in what would go on to be the game’s deciding goal.
Speaking to the BBC after the match, Ancelotti spoke of the work that has gone into making his side so dangerous from set plays.
“We did very well (in our) last few games,” said the Italian. “Brilliant performances (and) fantastic results. We showed more consistency.
“This season we started well, then we had a difficult moment, but right now I’m really pleased.
“We have fantastic players on set-pieces we score lots of goals. We work on this because we are very dangerous.
“We are pleased; the position in the table is really good. But as I said last week it is not the end of the season, we have to keep fighting.
“But it was a top, top performance today.”
Calvert-Lewin reveals Arsenal weakness
Calvert-Lewin didn’t register his name on the scoresheet, but played a vital role in Rob Holding’s own goal.
The in-form centre-forward was over the moon with his side’s battling display, and also revealed they intentionally targeted a perceived Arsenal weakness of defending the near post.
“There’s only 2,000 of them in [fans] but you can hear they are happy,” he said. “We dug in to a man, we didn’t panic and took our chances.
“Yerry Mina is a massive threat in the air, if the delivery is on the money he’ll score. We targeted the near post, that’s where their weakness is and we got a goal from it.
“There’s more to come from me, I am learning my craft. I want to be consistent week in week out.”
