The Swedish international made an impressive performance in the match and made several crucial saves for Fredrikstad who won the match.
TV2 says the Scottish giants Celtic watched him at Fredrikstad Stadion on Saturday and Shaaban is open for a move to Scotland.
He told Swedish newspaper Aftonbladet: “If something comes up, we will have to see what happens. I will not close any doors.”
German side Wolfsburg were also at Fredrikstad Stadion on Saturday.
He added: “I have holiday in July and then I will think through my future. I have a son in Stockholm that I have to think about. We will have to see what the best solution is.”
Shaaban has just over a year left on his contract with Fredrikstad.
