Mourinho reminded his former Chelsea players that they were capable of beating United - because he taught them how to do it.
Chelsea go into sunday's game with their hopes of stopping United from retaining the title slim indeed. However, Mourinho said that he ingrained a mentality in his former Chelsea players that they could beat Alex Ferguson's team.
In his three seasons and two months at Chelsea, Mourinho's charges won five out of 10 games they played against United in all competitions and, Mourinho pointed out, Cristiano Ronaldo never managed to score.
