‘Nana’ signed with Boston City FC on October 21, 2016 from local NPSL rivals the Rhode Island Reds.
In 2017, he led the Lions with 13 goals scored, finding the net 12 times in the NPSL, including two hat-tricks, and once in the Lamar Hunt U.S. Open Cup. He also led the team with 7 assists and in minutes played (1,136). He was twice named to the Football Manager NPSL Team of the Week and was named Mitre National Player of the week after scoring a hat-trick against his former club on May 13.
One of only two players to start every match, Nana was loaned to Ferroviaria of the Brazilian Campeonato Paulista first division following the season.
The Liberian-born midfielder produced a stunning first campaign in the NPSL as a member of the Reds, winning the league’s Mitre Golden Ball award as the 2016 MVP, and was named to the NPSL All-Star first team, alongside Boston City’s Michael Bustamante and Gabriel De Souza.
Addai also finished the 2016 regular season as the joint Puma Golden Ball winner having scored an impressive 18 goals in only 15 matches. Two of those strikes came in a Boston City 3-2 defeat of his former club, Northeast Atlantic Conference rival the Rhode Island Reds, when he curled home an impressive free kick and was also on target from the penalty spot.
Addai has represented the Liberia Under-23 national team and has played professionally in both his native country and Ghana, where he arrived having played soccer in a refugee camp during the Liberian civil war.
He played for Accra’s Sovereign Academy for five years in Ghana before joining Buduburam FC and Bago FC for one and two years respectively. He returned to Liberia after the war, but later made the decision to come to America to follow his soccer dream.
