Coventry City manager Andy Thorn has said that the Sky Blues need a cutting edge up front after City's 1-0 defeat at Derby County this afternoon.
Speaking to the Press Association, Thorn said: "I am really disappointed to be losing Lukas, it's a big blow for us.
"Alex comes in on Monday and I would like to bring some more in as well.
"I didn't think there was anything between the teams and we acquitted ourselves well but I think it's evident what we need. We need someone who can put the ball in the net.
"It's about fine lines, I didn't feel we were under any severe pressure but at the same time, I didn't feel we had a massive cutting edge. That's how I've felt for a while now and something needs to be done about it.
"We didn't have that killer instinct and although we had some great opportunities, a lack of quality in front of goal was evident. If we had that killer instinct in front of goal we would be in the top 10."
