The Toffees beat the struggling Black Cats at Goodison Park on Saturday, but the Dutch coach was not entirely happy with the performance
Ronald Koeman was not impressed with Everton's second-half performance against Sunderland despite going on to win the Premier League match 2-0 at Goodison Park on Saturday.
Everton were dominant in the first period and deserved their 1-0 lead at the break, after Idrissa Gueye scored his first goal for the club with a well-taken finish.
But rock-bottom Sunderland were brighter after the interval and Koeman believes that was as much down to his side's play as it was the visitors' improvement.
