The Hammers have been busy this summer and the striker is pleased with their business.
The Hammers have been busy in this transfer market so far, with new manager Slaven Bilic having brought in a number of new faces to reinvigorate his squad.
So far, Dimitri Payet seems to be the most exciting of those players given his performances in pre-season so far but the likes of Angelo Ogbonna, Manuel Lanzini and Pedro Obiang have all added serious competition to the West Ham side.
And Sakho believes that new level of competition will push everyone to do better next season as they seek to guarantee a place in the first team.
“It's the quality that counts, the quality that we're able to make the most of,” he told whufc.com.
“It's also good that there's a little more competition for everyone, it's going to push everyone to give their 100 per cent to try to play.”
Still a couple of signings being targeted
While West Ham have been so busy this summer, it is fair to say they still need a couple of more signings ahead of the new season.
It is something clearly in their thinking as well, with owner David Gold having told Sky Sports that they are now targeting another striker as well as trying to secure a deal for Alex Song.
The striker position will likely be the most prevalent of those positions, with Enner Valencia having picked up and injury and Andy Carroll still not fit. Who they can target though is a big question, with the market being short on top forwards.
Charlie Austin looks the most likely target, but his big asking price may prove a stumbling block in any move. If the Hammers would be willing to meet that, is yet to be seen.
