Everton come forward through Steven Naismith in pursuit of a fifth. He passes to Luke Garbutt, who then loses possession. That's probably the last attack of the game.

Three minutes of added time and Everton are looking good to head back home with a three-goal cushion ahead of the second leg.

Worth remembering that Young Boys were ridiculously strong at home. They had scored 13 goals and conceded just one in their five previous Europa League matches in Bern this season and have been well beaten tonight.

It promises to be some atmosphere at Celtic Park.

That's Romelu Lukaku's last action of the game and he gets a deserved round of applause as he heads off the pitch with three goals to his name.

Christian Atsu, who was player of the tournament at the Africa Cup of Nations, is on in his place. He scored an absolute belter at the Afcon, worth a look if you have not seen it!

Steven Naismith is nails. He runs off his injury and moments later Everton are so close to a fifth. Romelu Lukaku powers away from the home defence and tries to lift the ball over Yvon Mvogo, who makes a great save.

Steven Naismith is down clutching his leg after overstretching to challenge for possession. The result may be good, but some of these injuries may be a concern for Roberto Martinez.

Looks like Christian Atsu, fresh from returning from the Africa Cup of Nations where he helped Ghana to the final, is about to come on.

Yellow card for Romelu Lukaku. Not sure what for, even he doesn't seem to know what for as he shrugs his shoulders at the referee in disbelief.

Scrap that, they get forward as Romelu Lukaku goes for a fourth but he is offside as he heads wide from a cross.

Alexander Gerndt again has a chance, but the effort is blocked for a corner. Everton are not being adventurous now they are down to 10 men.

Kazim Kazim-Richards (formerly Colin in his days in English football) has bagged an equaliser for Feyenoord in Roma, cancelling out Gervinho's first-half strike to leave the scores locked at 1-1 at the Stadio Olimpico, while Hulk has given Zenit St Petersburg a 1-0 lead at PSV Eindhoven.

A brace from Bas Dost has put Wolfsburg 2-0 up against Sporting Lisbon and a Kenneth Petersen own goal has increased Club Brugge's lead to 3-0 at Aalborg while Jaba Kankava and Ruslan Rotan have put Dnipro 2-0 up at home to Olympiakos.

Torino still have a 2-1 advantage over Athletic Bilbao while Napoli have not yet extended their 3-0 lead at Trabzonspor in the second half.

A fine introduction to the game by Alexander Gerndt as the former Swedish player of the year meets a cross to volley a shot straight at Tim Howard. A little more to the left or right and that would have been 4-2.

Antolin Alcaraz is on for James McCarthy as Robert Martinez makes his second change. Young Boys also make a change as Milan Gajic is replaced by striker Alexander Gerndt.

Romelu Lukaku should have his fourth! Substitute Luke Garbutt crosses low from the right and the bounce on the artificial pitch catches out the Young Boys defender but also surprises Lukaku, with the ball bouncing off his foot and wide from barely four yards out.
