The Frenchman said: "Last year it was at midnight - and we are ready to stay up all night this time if it is needed. We have still a long time to go.
"For a while they all talk the talk and nothing happens, then in the last four or five days every half-an-hour there is a headline saying someone has signed somewhere.
"When you have experience of transfer dealings, you know that as long as something is not signed you know it can change very quickly so you can look very silly, so you don't want to come out and announce it.
"We are out to look, if we find the right players we will do it, one or two.
"However, I believe it's more interesting for us to focus on our strengths and quality rather than looking outside. I know it makes headlines, but it doesn't make you win games."
