Slaven Bilic says Newcastle United are "dangerous" – despite the club's lowly position.
Bilic brings his West Ham United team to St James's Park on Saturday.
Newcastle are 19th in the Premier League and a point adrift of safety.
But Bilic – whose club is fifth in the table – is wary of Steve McClaren's side, who drew 3-3 with Manchester United on Tuesday night.
"They had a slow start, but now they are doing OK," said Bilic.
"They are a massive club. They are improving. They have a very good roster of players.
"Going forward they have many options, they are very dangerous. They had a good comeback against Man United so they are on a high.
"It should be a good game, at a great stadium, so we are really looking forward to it.”
Bilic also confirmed that former Newcastle striker Andy Carroll was facing three weeks on the sidelines with a hamstring problem.
