Everton boss Roberto Martinez expects deadline-day signing Senegal international Oumar Niasse to adapt quickly because of local connections.

"He is a player we have been tracking for a long time, the first time we saw him was in the first week of September and since then we have been very close trying to find out about his character," said the Spaniard.

"He has a very specific family situation as his wife is English and from the north west and he has been following our team and the way we play and it was a real conscious desire to join us and that has been important.

"We didn't think he would become available but when we saw he was we moved very quickly.

"It was a sign of being precise in what we wanted; we moved two players from the first-team squad (Steven Naismith was sold to Norwich and Aiden McGeady loaned to Sheffield Wednesday) and we brought in a 25-year-old who has been successful in two European leagues.

"He is not back-up for anyone, he has his own ability and is someone who can stretch defenders and can cope with the physicality of the Premier League."
