The Amsterdam side were unable to hold on to their early lead as the Swedish youngster netted his second hat-trick of the season to help the home side to the full three points
The Amsterdam side opened the scoring after a superb shot from Christian Eriksen, but John Guidetti restored parity after a questionable spot kick, before gifting the hosts the lead with a tap-in. Otman Bakkal then made it three for the hosts shortly after the break, with Dmitry Bulykin netting the 3-2 with 15 more minutes to go. However, Guidetti got his hat-trick shortly after to put the match to bed.
Ajax started the match the better side of the two, but the first chances were for Feyenoord. John Guidetti tried his luck twice from outside the area, only to see shot stopper Kenneth Vermeer collect the ball with ease on both occasions.
The guests then got a good chance to break the deadlock after a good individual action from Vurnon Anita, but Feyenoord goalkeeper Erwin Mulder proved his worth with a fine save.
Ajax did go 1-0 up 18th minute after a quick counterattack following a Feyenoord corner. Christian Eriksen collected the ball just inside the hosts' half and skipped past two opponents before curling in a left footed shot in the far corner. Lorenzo Ebecilio should have doubled the Godenzonen's lead shortly after, but he failed to beat Mulder in a one-on-one situation.
Feyenoord started pressing for the equaliser after that and were rewarded at the half-hour mark. Guidetti went to the ground after what seemed to be a legitimate challenge from Jan Vertonghen, but the referee decided different and awarded the home side a penalty. Guidetti stepped up to take it and found the top corner to restore parity.
The 1-1 appeared to be a real confidence boost for the Stadionclub and Guidetti doubled his personal tally in the 41st minute. The Ajax defence failed to clear the ball after a header from Otman Bakkal, and the young Swede tapped home from close range to gift Feyenoord the lead.
Feyenoord continued to push forward after the interval and added a third goal in the 49th minute. Guyon Fernandez danced past two opponents in the centre of the pitch before setting up Bakkal on the edge of the area. The PSV loanee controlled the ball superbly, and then fired home with a low volley.
Ajax didn't give up though and got a chance to peg one back via Theo Janssen around the hour mark, but the midfielder's shot was blocked by Ron Vlaar and eventually led to nothing.
The Amsterdam giants did peg one back in the 80th minute after a howler form Mulder. They Feyenoord shot stopper hesitated too long after a backpass, and his clearance deflected off Bulykin into the net for the 3-2.
Nevertheless, the hosts weren't too impressed and restored their two-goal lead only minutes later. Kamohelo Mokotjo found Guidetti inside the area after a quick counterattack, and the Swede kept his cool to net his third of the afternoon.
Feyenoord sit joint-fourth in the Eredivisie table at the moment with 34 points from 19 games. Their next match is the trip to NEC on February 5.
