Demba Ba capitalised on Steven Gerrard's slip on the stroke of half-time to give the visitors the lead, while Fernando Torres raced through to set up Willian for an easy second late on to seal a famous victory.

"We just couldn't find the breakthrough - there were probably two buses parked today, never mind one," he told reporters.
"Jose's happy to work that way, to play that way, and he'll probably shove his CV in front of me and say it works, but it's not my way of working.
"I like to take the initiative in games, try to dominate and let players express themselves.
"Our game is based on [being] offensive, being creative, as opposed to stopping.
"It [Chelsea's approach] is a defensive style, the polar opposite to how we work, and hopefully over time our offensive mentality and aggression will get us long-term results," he added.
"It's not difficult to coach to put 10 players right on your 18-yard box but it's much harder to try and break through it and they defended it well.
"We were the team that wanted to win the game. It was difficult because they played with a back six right from the off.
"We found it difficult to break them down, but it wasn't nerves. It was just that final ball and maybe that bit of luck that we needed so we're obviously disappointed with the result."
Mourinho, however, remained bullish about his team's performance, insisting they deserved to win and challenging the assertion that his tactics were defensive."The best team won," he told reporters. "The team that deserved to win won.
"Defensive display? I am confused what the media thinks about defensive displays. When a team defends well you call it defensive."
The Chelsea boss also brushed off criticism that his team looked to waste time and break up Liverpool's attacking rhythm throughout the game.
"Time-wasting? What is that?," he added. "We never spoke about this when we played lots of matches this season. Now we're speaking about it."
