Earlier this summer, the 18-year-old moved to West Ham from Premier League rivals Manchester City, where he was a member of their Elite Development Squad.
Samuelsen earned the contract at the Hammers after impressing coaches at the West Ham United Academy while on trial on the back end of last season.
The teenager made his debut for the Hammers in a pre-season friendly game against Peterborough United at London Road on Saturday.
The match ended in a 3-3 draw, and Samuelsen was pleased to have played with forwards Sakho and Maiga.
“Playing with Diafra and Modibo in the front three was a brilliant experience – they’re great players so they make it easy for me,” the youngster told West Ham’s official website.
“I know where they are and they have good movement. It’s a good connection.”
Sakho started the 2014-15 season for West Ham brilliantly following his move from French club Metz last summer.
At one stage it looked as though the 25-year-old Senegal international would score 15 to 20 goals in the Premier League, but he ended up with 10 in 23 league appearances.
According to The Daily Mail, Manchester United are interested in signing Sakho this summer.
Maiga has been on the books of West Ham since 2012, but he is not guaranteed a place in the starting line-up.
The Mali international, who can feature as a striker as well as a winger, played on loan for Metz during the 2014-15 season.
