Isaac Hayden's 94th-minute header secured three points for the Magpies.
Mason Mount believes Chelsea did all they could to secure a victory against Newcastle United - who handed them a sucker punch in the dying minute at St James' Park.
Frank Lampard's Blues came up against a disciplined side on Saturday as their 19 attempts on goal amounted to nothing against the Magpies.
Eventually, Isaac Hayden's 94th-minute header secured three points for the homeside, and following the game Mount expressed his disappointment on the result.
‘It’s a tough one to take,’ the midfielder said as chelseafc.com reported. ‘Even a draw we would have been disappointed with. We had a lot of possession, we created a lot of chances, but when we score no goals we can’t say anything.
‘They did unbelievable to defend the whole game, making blocks, winning tackles, and in football anything can happen. They then go to the other end of the pitch late on and score.’
This was Chelsea's fourth league defeat without scoring a goal since late November, and Mount said they need to look at ways to break teams who park the bus.
‘We spoke after the game and we thought we gave everything we could,’ the 21-year-old said. ‘I thought we created loads of chances. In some other games we didn’t create as many. We had some shots on target, but when the team are defending that well and that deep it’s hard to break them down.
‘We had a lot of possession. They had a lot of bodies behind the ball. We put crosses in, they defended it, so we need to look at what ways we can maybe add to our game to score these goals.
‘It was hard for us to get the ball in the areas we want and create chances. Credit to them that they defended so well, I thought we gave it our all and worked hard throughout the game, but in football anything can happen.’
