Ablett died aged 46 on New Year's Day after a 16-month battle with non-Hodgkin's lymphoma.
Liverpool manager Kenny Dalglish and Everton boss David Moyes were present at the city's Anglican Cathedral along with many of Ablett's team-mates - including John Barnes, Alan Hansen, Mark Lawrenson, Duncan Ferguson, Matt Jackson and David Unsworth - and other contemporaries from the 1980s and early 1990s.
The likes of Everton stars Phil Neville and Tim Cahill were joined by former Toffees managers Joe Royle and Howard Kendall and ex-Reds boss Rafael Benitez.
Roy Keane, who briefly worked alongside Ablett at Ipswich just before his illness was diagnosed, was also present along with England Under-21 manager Stuart Pearce
The coffin of Ablett, the only man to win the FA Cup with both Merseyside clubs, was carried into church to You'll Never Walk Alone and left to Everton's anthem Z-Cars.
He leaves behind a wife, Jacqueline, and five children.
