Di Matteo could be the man to lead Chelsea into next season and beyond.
"I think it (the result) was fantastic for Chelsea, it was a huge performance by them and they deserve every credit," he said.
"He has done great and I think Robbie would obviously be delighted he has the opportunity that has been presented to him - he had to grab it with both hands and that is what he has done.
"I think the fact he was in and around the group with the previous manager meant he understood the issues the group had with the previous manager and he has been able to go in and, from the outside looking in it, it looks like he has been able to address issues.
"Who knows (if he will get the job). He has done his prospects no harm whatsoever. I think he has done everything that could be asked of him and that is credit to him because it was difficult circumstances as he was involved with the previous management team but he has come through."
