"It showed the ambition of the club to prepare for the future," said Dicko, who was himself a January transfer window signing a year ago. "He has done really well in League One this season and it can only help me. I think I can play well with him."
Afobe, who scored on his debut in the 2-0 win over Blackpool on 17 January, started alongside Dicko for the first time in last Saturday's 2-2 draw at Bolton.
Dicko scored Wolves' third-minute opener at the Macron Stadium, making him joint top-scorer with Bakary Sako with seven goals.
