Man Utd have completed the signing of another Belgian goalkeeper - although it's too early for him to replace David de Gea. Manchester United have signed Belgian goalkeeper Ilias Moutha-Sebtaoui from Standard Liege. The 16-year-old, who was reportedly scouted by Chelsea, has signed a three-year contract with The Reds. Moutha-Sebtaoui joins fellow compatriot and teenager Indy Boonen, who also joined United earlier this year.
