Speaking to West Ham TV, Sam said “It has been a good window for us.
“There are some players of development among our signings in young Sakho and Diego Poyet, particularly those two. There, we are hoping to develop them this season, but it may not be this season.
“All the others, we’re hoping will adapt to be very successful, particularly Enner Valencia. However, he is the most difficult one coming from South America and from a club in Mexico, so we may need to be a little more patient with him.”
