Arsenal boss Arsene Wenger refuses to be pressured into buying players in the remaining days of the winter market.
Manchester United exposed Arsenal's deficiencies at fullback for yesterday's win.
But Wenger insisted: "Spending the money is not the target, to buy good players is the target. We need our players back. People are not conscious that we miss 10 players. When you see what we created in the second half without [those injured] players, it is important to get the players back."
