West Ham United boss Sam Allardyce has hailed the impact of his summer signings this season.
Diafra Sakho has been the most eye-catching of the Hammers' new arrivals but Enner Valencia, Alex Song, Morgan Amalfitano and Aaron Cresswell have all impressed in the early part of the season.
"I have to say they have surprised me," Allardyce said.
"If you have one or two doing it from the start, particularly from abroad, then you are satisfied - but all of them have had an impact.
"Valencia and especially Sakho with the goals, Mauro Zarate has done well, and Aaron Cresswell looks as though he belongs in the Premier League.
"We all know about Songy and he is not even fit now - when he gets fit we will see even more from him."
Allardyce continued: "We have a very welcoming dressing room for new players here. (Captain) Kevin Nolan builds a strong bond between the players and because of that togetherness and because we try to do as much as we can for the players, they grow willing."
