Newcastle booked their place in the Intertoto Cup with victory over Premiership champions Chelsea.

Defender Titus Bramble scored the only goal of the game when his fierce volley flew past Blues goalkeeper Lenny Pidgeley in the second half.
Chelsea had two goals disallowed, with William Gallas deemed to have handled the ball into the net before Shaun Wright-Phillips was ruled offside.
Newcastle's Stephen Carr was sent off after appearing to kick Lassana Diarra.
Magpies' caretaker boss Glenn Roeder, who many believe will be installed as the permanent successor to Graeme Souness this week, would have been pleased with his side's efforts in their final game of the season.
Newcastle were just six points above the relegation zone when they sacked Souness in February, but have since won 10 of their 16 Premiership and cup matches under the leadership of Roeder.
Their renewed confidence was clear to see at St James' Park on Sunday, often outplaying a reshuffled Chelsea pack, who appeared merely content to see out their final 90 minutes of another successful Premiership campaign.
Newcastle would have been pleased to see the return of Turkey midfielder Emre who was at the heart of all the home side's good movement.
He should have opened the scoring after three minutes of the match, but saw his 25-yard-shot swerve over the Chelsea crossbar.
The Blues defence was kept busy during an action-packed first-half, in particular stand-in keeper Pidgeley.
The Chelsea keeper was thrust into the starting line-up after Carlo Cudicini appeared to hurt his ankle during the warm-up.
Pidgeley had to stay alert to watch two long-range shots from Nolberto Solano go wide, before a backpass from his own player, Joe Cole, nearly caught him out.
Solano, who was also having a major influence on the game, was taken off late in the first-half after what appeared to be a calf injury.
Chelsea began to find their gears in the second half after being on the back foot for most of the opening 45 minutes.
Jose Mourinho made six changes to his side, leaving out Frank Lampard, Didier Drogba and Hernan Crespo, and it took a while for the makeshift side to gel, but the introduction of striker Carlton Cole and midfielder Wright-Phillips appeared to add some bite to the attack.
The Blues had the ball in the net on two occasions, but referee Mike Riley disallowed Gallas' and Wright-Phillips' efforts.
Chelsea were in the ascendancy, but it was Newcastle who took the lead through the unlikeliest of source.
Emre's corner was met by the head of Amady Faye. The Senegal international nodded the ball into the path of Bramble, who acrobatically volleyed the ball past Pidgeley.
More drama was to follow when Carr was shown a straight red after appearing to aim his boot at Diarra, who was lying on the ground at the time.
A tense final few minutes followed, but Newcastle held on for victory.
Newcastle caretaker boss Glenn Roeder was delighted after leading his side to a place in the Intertoto Cup:
"I feel exactly the same as I have always done when I come up here after we have won a game, very satisfied," said Roeder.
"It's a shame the season is finishing, isn't it? We have come from nowhere.
"We have come from nowhere to get a stab at the Uefa Cup next year via the Intertoto Cup."
Chelsea boss Jose Mourinho was left fuming with two decisions by referee Mike Riley:
"There should have been a penalty when Jean-Alain Boumsong clashed with Ricardo Carvalho. Now Carvalho has to go to hospital as a result," he said.
"Celestine Babayaro should have got a red for his tackle on Arjen Robben."
"I hope the referees go on their holidays now and come back with new thoughts for next season."
