The Dream Team VI handler has invited the Blaugrana defender for the Africa U23 Championship billed for Senegal in November
The former Super Eagles handler had earlier called up 51 players to camp ahead the African Olympic qualifying tournament in Senegal.
According to Siasia, both players were given a nod to fight for a place in his team, as well as build a formidable squad that will make the country proud.
“After the All Africa Games in Congo, I noticed some departments of the team that needed to be worked on, so I decided to extend my dragnet in search of players who have shown interest in playing for Nigeria in a bid to building a solid team that will be the pride of all Nigerians," Siasisa was quoted by the Nigeria Football Federation website.
The U-23 supremo disclosed that no player will be released from the camp as the team begins preparation on Monday, October 26.
Nigeria have been drawn in Group B of the tournament where they will face Egypt, Algeria and Mali while hosts Senegal headline Group A which has South Africa, Zambia and Tunisia.
The tournament is the final qualifying competition for the 2016 Olympic Games in Rio, Brazil. The top three teams will qualify for Rio 2016.
