Sunderland manager Dick Advocaat has told The Chronicle that midfielders Seb Larsson and Jordi Gomez both struggled against Everton.
Goals from Danny Graham and Jermain Defoe handed Sunderland the win, pulling them out of the relegation zone, though they still lie just two points clear of the bottom three.
It was a largely positive afternoon for Sunderland, who saw Hull City and Newcastle United fail to win following the final whistle at Goodison Park.
However, manager Dick Advocaat wasn't totally happy with the display, singling two players out in an interview with The Chronicle after the game.
Midfielders Sebastian Larsson and Jordi Gomez were both criticised by Advocaat for their displays against Everton, with the Dutchman suggesting that only Lee Cattermole helped Sunderland gain control of the battle in midfield against Roberto Martinez's Toffees.
"Everton outplayed us, but our back five – including the goalkeeper – did really well. Some of the players played well last week but had more problems against Everton," said Advocaat.
"We just couldn’t control the midfield, aside from through Lee (Cattermole). (Seb) Larsson and Jordi (Gomez) had some problems today. At the end, though, we have the three points," he added.
