The Chilean boss praised his new arrivals as the Yellow Submarine prepare to meet the hammers.
""[Joseba] Llorente, [Ariel] Ibagaza and Edmílson are our three major reinforcements, and they will surely play a supportive role," he said.
"They have been integrated to the organisation of the team very quickly."
Looking ahead to tomorrow's friendly in London, he said, "These matches are used to try to make the team as homogenous as possible.
"At this point we're looking neither for results nor performances, but preparation of the whole squad, not just one team.
"After West Ham we'll then work in Jerez for a while, and then there's the Carranza trophy, after which we'll finish off with physical and technical work.
"After that will be two more friendlies at the Madrigal, and the final week will be for adjustment."
