When questioned about whether Christopher Nkunku could fill in for Jackson during the busy period, Maresca said that the Frenchman could play as the number nine but added that his wingers Pedro Neto, Noni Madueke, Jadon Sancho and starlet Tyrique George could also fill the vacant spot.
The Italian said: "Christo is a solution but not the only solution. I said many times I consider Christo a very important player from the start.
"Now also with the transfer window closed, everyone is here and he can help us until the end. We are working to find a different solution. It can be Christo but also a different kind of player."
"Could a winger play centrally? Could be a solution. Pedro, Noni or even Tyrique, they can try and be a solution for us. Jadon has different kind of skills. When you don't have a proper nine, you need to use a different kind of nine but you need to change the way you play. We will find a solution."
