West Ham United boss Avram Grant is confident his new signings will prove themselves.
Grant saw some positives from their defeat to Chelsea on Saturday.
He told whufc.com: "We have a lot of positives to take and if we continue like this, the future will be good.
"All of the new players that we had brought something to the team. Obinna and Barrera are players that can quicken the attack. Since the transfer window shut, most of the players had been on international duty. This week we will train for the first time together and I am very happy with my new players."
