Di Matteo has been in caretaker charge since Andre Villas-Boas was dismissed, and despite winning the FA Cup and Champions League it is still not clear whether or not Roman Abramovich will reward him with the permanent job.
However, Heynckes is calling for the Italian to be given a permanent contract at the club, telling reporters: “I congratulate Chelsea on their victory. If you wish me to say something about Roberto Di Matteo it is that Chelsea should give him a three-year contract."

The Bayern coach has admitted they only have themselves to blame for not lifting the trophy in front of their own fans, despite dominating for 120 minutes.
Heynckes added: “Chelsea played the way we thought. We must blame ourselves for having so many goalscoring opportunities without being able to score until the 83rd minute."
The 67-year-old exonerated Arjen Robben from blame after the Dutchman missed a penalty in extra-time and then opted not to step-up in the shoot-out.
Heynckes remarked: “You can understand if he didn't score the penalty in extra-time that he may have lost some self-confidence to participate in the penalty shoot-out. That is quite easy to see."
