No stopping goal machine Calvert-Lewin
Everton 4 Brighton 2
In-form Dominic Calvert-Lewin celebrated his first England call-up by scoring in a fourth successive Premier League match as Everton returned to the top of the table for 24 hours at least with this win.
Of greater interest to fans here was an injury to Séamus Coleman, which makes him a major doubt for the Euro play-off in Slovakia on Thursday. He lasted 58 minutes before going off with what appeared to be a hamstring injury.
Calvert-Lewin's ninth of the season makes him the leading scorer in Europe's top five leagues.
However, Jordan Pickford had another afternoon to forget.
The England No 1 was at fault for Neal Maupay's equaliser, failing to hold Leandro Trossard's volley hammered into the turf - his third mistake in as many matches having made two in the Carabao Cup win at Fleetwood. That mistake allowed Brighton level it up.
Pickford has made nine errors leading to goals since the start of the 2018-19 season, more than any other player.
He was grateful to the club's Colombian connection, as James Rodriguez's free-kick presented Yerry Mina with his first Goodison Park goal just six minutes later, with Rodriguez himself then scoring twice after half-time.
Fortunately for Ancelotti, he has no such worries at the other end of the pitch where Calvert-Lewin, after passing up a relatively straightforward chance a man in his form should have taken after 82 seconds, continues to excel.
The striker has netted in five of his six matches this season, including two hat-tricks. In doing so, he became the first Everton player to score in the first four matches of a Premier League season.
His hanging, far-post header, from which he scored via Gylfi Sigurdsson's 16th-minute cross to give the hosts a deserved lead, is fast becoming a trademark.
But Pickford's misdemeanours and misjudgements continue. There was no one else at fault for an equaliser completely against the run of play.
Instead of opting to simply tip the high-bouncing ball over the crossbar, he attempted to catch it, rather like his clanger in the Merseyside derby at Anfield in December 2018, which led to Divock Origi's last-minute winner.
But, on a wet day, the ball slipped from his grasp, presenting Maupay with a simple tap-in.
Mina spared his embarrassment by heading home Rodriguez's inswinging free-kick for his third goal of 2020.
Much of Brighton's game-plan appeared to involve going in hard on both Everton's playmaker and Richarlison, who passed a late fitness test on an ankle injury.
The Brazil forward was forced off 25 minutes into the first half after a crunching-but-fair tackle by Tariq Lamptey.
But there was no stopping Rodriguez, fouled for the free-kick which led to Mina's goal, and he made the game safe with two far-post finishes from crosses by Alex Iwobi and Abdoulaye Doucoure.
Despite a 100 per cent record and 12 goals in four league matches, the international break could not come at a better time for Ancelotti, with nine first-teamers now on the treatment table after this.
Yves Bissouma volleyed home an added-time consolation.
