Everton manager Roberto Martinez praised referee Lee Mason for taking swift action after a reported incident of spectator racism during the Premier League side's FA Cup win at Carlisle.
It came after Arouna Kone fired Everton into an early lead at Brunton Park, setting the visitors on the way to a 3-0 victory. Aaron Lennon added the second goal and Ross Barkley fired the third.
A public address system message announced any abuse would not be tolerated, and Cumbria Police issued the same message on Twitter, asking anyone with information to report it.
Mason spoke to Martinez about the abuse aimed at Everton players.
"I thought it was dealt with in a very good manner," Martinez told BT Sport.
After speaking to Carlisle boss Keith Curle, it was agreed there should be a warning to spectators.
"We agreed to make an announcement. I thought the referee was very good in how he dealt with that," Martinez said.
"It was just a reaction, something that we don't want to see. It was just a reaction to the celebration of the goal and that was it. It would be wrong to highlight such a moment in an enjoyable footballing festivity."
Asked about his team's display, Martinez said: " I thought we played well and controlled the threat Carlisle could bring and don't underestimate the clean sheet against a team that can put the ball in the box very quickly.
"Scoring three goals and creating good chances, overall it was a well-worked performance."
England midfielder Barkley scored the pick of the goals, with the help of a deflection, and was applauded off by both sets of fans when substituted in the 75th minute.
Martinez said: "He's a stylish footballer and any football fans love to see that skill."
