Gylfi Sigurdsson is on the verge of completing his highly anticipated move from Swansea to Everton after passing his medical.
"I have seen the doctor and there is no problem," said Everton boss Ronald Koeman.
"Still he needs to sign, but I saw him in the Blue!"
Koeman told a press conference: "We worked a long time to get this deal in, he was one of the key players to bring in.
"We need players who will bring productivity to the team.
"We lost Romelu Lukaku and we lost 25 goals, we need more players than one to get that number of goals. He is that type of player with that productivity.
"He knows the Premier League, he had a good season at Swansea and in his position he is one of the best in the Premier League."
