Police Union secured their fifth signing in the January transfer window with the capture of ENPPI's Nigerian striker Minusu Buba. ENPPI said on Friday that they agreed to sell Buba to Police for $ 150,000. "Given that we signed Buba on a free transfer last summer, selling him with that amount is very profitable," ENPPI football director Alaa Abdul-Sadek told the club's official website. "We also wanted to make room for new arrival Zeka Goory because regulations permit us to sign just three foreigners and we already have Manu and Vincent Die Foneye in our squad." Ivorian striker Zeka Goory, who invoked a release clause to leave Petrojet and join Wasl in September, moved to ENPPI after failing to prove his worth at the UAE club. Fifth Signing Buba, who scored three goals for ENPPI this season, is Police's fifth arrival in the January transfer window. They signed Tamer Riad, Ahli midfielder Hassan Mostafa and Baladeya duo Gamal Gad and Mohamed Naguib as they aim to retain their top-flight status after sealing promotion last season. Police, who caused a huge upset by beating Cairo giants Ahli in November, lie 11th in the Egyptian Premier League table with 16 points, just one above the relegation zone.
