AC Milan defender Simon Kjaer says they must learn from their 3-0 friendly defeat to PSV Eindhoven.
The match marked their final midseason friendly before Serie A's resumption.
Kjaer said: “We made too many technical mistakes, it's not what we wanted. We'll improve by the 4th. It's not a question of concentration or maturity, I saw the whole team working in all the training sessions. In the last three games we lost, this will be changed."
On the past year, the Dane added: “We'll do everything to get as many points as possible.
"We still have everything to play for, we are Milan, we won the Scudetto this year, I'm sure the fans will be with us until the end."
