Adams is Southampton’s second major signing ahead of the 2019-20 season, following the arrival of Malian winger Moussa Djenepo.
“Both Adams and Moussa Djenepo are dynamic players with the level of enthusiasm and hunger we are looking for that can help us improve as a team,” Hasenhuttl said.
“Che fits the profile of player we want to bring to Southampton and is very driven to show what he can do at the highest level,” Saints manager Ralph Hasenhuttl told the club’s website here
“We have been monitoring and enjoying his progress for some time now. He has shown a desire to join us above all other clubs, which shows the positive reputation Southampton has built for developing young players.”
