Jay-Jay supershow sinks Villains
The Nigerian wizard signed off in style before jetting off to Tunisia with a two-goal salvo that left Wanderers with one foot in next month's final.
The former Paris Saint Germain star gave the hosts the perfect start by curling home a delightful free-kick with just two minutes on the clock, after Peter Whittingham had been debatably penalised for a foul on Kevin Nolan.
Nolan himself then sent the home fans into raptures with a well-taken second just four minutes later.
The midfielder latched on to a knock-down from Kevin Davies and, after beating a hesitant challenge from Olof Mellberg on the edge of the box, fired a crisp shot into the bottom corner from 18 yards.
Two became three with barely a quarter of an hour gone, Davies caused more havoc in the Villa defence by out-muscling Dion Dublin to nod on a Bruno N'Gotty free kick allowing Stelios Giannakopoulos to lash in a spectacular overhead kick.
A shell-shocked Villa gave themselves a much-needed lifeline five minutes later when Juan Pablo Angel out-manoeuvred Davies on the right touchline and fired in an attempted cross which sailed over the head of Jussi Jaskelainen and into the bottom corner.
The Finnish international custodian was then called upon to produce a fine smothering stop to deny Gavin McCann on the stroke of half time after a Gareth Barry cross found its way through to midfielder at the back post.
Angel did though claim a second ten minutes after the break, albeit in bizarre fashion - Jaaskelainen blocked an initial Whittingham effort, but Darius Vassell managed to guide in Barry's subsequent cross-cum-shot though a final touch off the Colombian ensured the ball bobbled in.
Bolton were furious that the goal was allowed to stand after protesting that Angel was stood in an off-side position when he got the decisive touch, and both sets of players squared up following a foul on McCann by Ivan Campo minutes later.
However, Wanderers regained their composure and moved further ahead on 73 minutes when N'Gotty was left unmarked from Djorkaeff's right-wing corner to power home a thumping header despite the best efforts of Lee Hendrie on the post.
Okocha then took centre stage and restored his side's three goal cushion with a wonderful second, drilling in a memorable 25-yard free-kick with the outside of his boot which left Sorensen clutching thin air and asking questions of his defensive wall.
The victory leaves Bolton favourites to clinch a place in their first domestic final since 1995 when they lost to Liverpool in the same competition.
