Young Black Cats defeated at Bolton.
Bolton Wanderers U18 3 Sunderland U18 0
Sunderland suffered defeat at the hands of Bolton in a friendly in the north west.
After a fairly even, goalless first period the second-half performance fell away for the young Black Cats.
They opened well and half chances fell to Lynden Gooch and Carl Lawson who shot just wide and the Wearsiders looked comfortable and in no real danger.
However, they were completely dominated after the break. The Trotters' first goal came when the visitors tried to play a short goal kick which was intercepted and banged in.
This was followed by a second which came from a corner with a Bolton player rising unchallenged to head home.
After this, Sunderland were always chasing the game and got caught on the break for the third and final goal which was scrambled over the line following a cross.
"It was a very disappointing second-half - after the first half we just didn't see it coming," said Sunderland coach Craig Liddle. "We will have to play far better in next week's derby against Newcastle."
Sunderland: Dixon, Burn (Lane, 60), McNamee, Gibbons, Reece Noble, Lawson, Martin, Agnew (Cartwright, 60), T Robson, Smith (Holland, 60), Gooch.
