Fabio Quagliarella scored a late equalizer as Juventus came from two goals down to draw 2-2 with defending champions Chelsea in the Champions League yesterday.

The Italy forward’s 80th-minute goal came only six minutes after coming off the bench, completing the Italian champions’ comeback after falling behind to a quickfire double from Oscar in the first half of the Group E match.

The Brazil playmaker marked his first start for Chelsea with long-range goals in a two-minute span just after the half-hour mark, the first deflecting off Leonardo Bonucci into the corner of the net and the second a superb curler from the edge of the box.

Arturo Vidal reduced the deficit in the 38th for Juventus, who were making their return to the competition after a three-year absence.

There was a celebratory atmosphere pre-match as members of the armed forces paraded around Stamford Bridge with the trophy won in dramatic circumstances four months ago — on penalties against Bayern Munich at the home of the German side.

Di Matteo has spent nearly £80 million during the offseason in adding a raft of creative, young midfielders and playmakers to his squad to replace the departed Didier Drogba and Salomon Kalou. Of the remodeled attack, only Eden Hazard has shone so far this season — but Oscar took his chance here.

Wearing the No. 11 shirt vacated by Drogba — the scorer of Chelsea’s winning penalty against Bayern — the 21-year-old Brazilian made an immediate impact in front of Chelsea fans who had only seen fleeting glimpses of him in three substitute appearances in the Premier League this season.

After showing some nice touches but little else in the first half-hour, Oscar received a short pass from Hazard and arrowed in a shot that took a looping deflection of Bonucci and nestled into the corner of the net beyond goalkeeper Gianluigi Buffon.

His second goal less than two minutes later was much less than down to luck and more an instinctive reaction after a loose control from Ashley Cole’s pass. Beating Andrea Pirlo to the ball, Oscar spun and curled a delightful effort into the top corner from just outside the area for a goal that was greeted with gasps by his jubilant teammates.

By that stage, Juventus — Italy’s best hope for the title this season after going 42 league games unbeaten in Serie A — had wasted great chances through Claudio Marchisio and Mirko Vucinic. The movement of diminutive schemers Sebastian Giovinco and Vidal also gave the home defense plenty of problems.

Vidal’s goal was avoidable, though, with Frank Lampard giving the Chilean midfielder too much time to cut inside and drive a low shot through the legs of John Terry and into the net.

It gave the visitors renewed hope and the second half started with coach Antonio Conte biting his nails in the stands, where he was banished due to a 10-month touchline suspension for match-fixing violations in Italy that was extended worldwide by FIFA last week.

Juventus seized the initiative as Chelsea retreated to deploy the tactics that served them so well in the competition last season — defending deep and hitting opponents on the counterattack.

Initially it worked with Juve running out of ideas up front despite the increasing influence of the bearded Pirlo, but Quagliarella was introduced in the 74th minute and equalized soon afterward.

John Obi Mikel was made to pay for a dreadful pass from the back, Marchisio slipping a pass through for his Italy teammate to run on to and slip a neat finish through Cech’s legs.

Lionel Messi scored two late goals to give Barcelona a 3-2 win over Spartak Moscow and start the Spanish team’s bid for a fourth Champions League title in eight seasons.

Spartak overcame Cristian Tello’s 14th-minute opener to lead 2-1, first leveling through Dani Alves’ own goal in the 29th. Romulo then struck in the 59th to give the visitors an unexpected lead.

But Messi, who equalled a Champions League record with 14 goals last campaign, tapped in Tello’s pass to make it 2-2 in the 71st and headed in Alexis Sanchez’s cross in the 80th to keep Barcelona undefeated in 17 straight home games in Europe.

Celtic drew 0-0 with Benfica in the other Group G game yesterday.

Michael Carrick scored an early goa and Manchester United hung on for a 1-0 win over Galatasaray in their Champions League opener despite sloppy play and a missed penalty from the English club.

Carrick put United ahead in the seventh minute as Alex Ferguson’s team looked determined to put last season’s disappointing group-stage exit behind it. But Galatasaray pegged United back after that and were unlucky not to equalize. The Turkish club hit the woodwork three times, had two penalty appeals rejected and forced a couple of good saves from David de Gea to leave Old Trafford scoreless.

Nani could have made the game safe for United in the 52nd but missed a penalty.

Toni Kroos’ powerful long-range strike got Bayern Munich off to a winning start in the Champions League with a 2-1 win over Valencia.

Kroos let fly to the top left corner with 14 minutes remaining, just as a defensive Valencia side threatened to equalize Bastian Schweinsteiger’s 38th-minute opening strike.

Valencia substitute Nelson Valdez then out-jumped two Bayern markers in injury time to head Jonathan Viera’s cross beyond Manuel Neuer for some late drama.

There was still time for Valencia defender Adil Rami to earn a second yellow card for bringing down Arjen Robben in the penalty area, and for Mario Mandzukic to miss the resultant penalty on his Champions League debut.
