West Ham boss David Moyes speaking to BBC MOTD: "I think you are always trying to improve the squad but that wasn't the reason we lost tonight. We have to analyse that.
"We had a good pre-season, we were feeling good after finishing the season well so we were disappointed with tonight.
"We need to get better with the players we have and they can be better, undoubtedly."
Newcastle manager Steve Bruce told Sky Sports: "I wouldn't say best week but when you come away from the Premier League and win 2-0 with two new signings scoring, it helps the cause.
"There was not much in it and we have a striker who scored typical striker's goal. Callum Wilson enjoys playing against West Ham and it was good to see them two get off the mark. We were worthy winners.
"We have been missing the goals, Callum will give us something different and makes the squad better. He can only help the situation.
"We have made progress, it is a long season and cannot get carried away but the last week has been a positive week for everybody, the impact the signings have made, the supporters in particular will like the look of them,
"That is certainly the best I have seen of Andy Carroll since the year he has been back. He has scored a coupe goals in pre-season and when he plays like that and he stays well, we know what sort of competitor he is."
