The Australian would like to see the under-fire Liverpool manager remain in charge, and alluded to football history from a rival club.
Despite a poor season which saw Liverpool finish sixth in the Premier League - culminating in the 6-1 thrashing at the hands of Stoke City on the final day of the season - and also finish without a trophy, along with an uninspiring run in Europe, Kewell has called for patience.
Kewell looked at the example set by Manchester United when it came to Sir Alex Ferguson's early years at Old Trafford, telling Sky Sports: “You have got to give it time. Brendan Rodgers is a good manager, I think he is doing a wonderful job. I think you just have to give him time. It takes time to win titles.
“If you want to go back look at Alex Ferguson, he had a terrible time at the start of his career when he went to United but look what happened when he got stood by, look at what he achieved.
“I think it is easy to criticise managers straight away, saying if it’s not working let’s get rid of them and bring someone else in, but you need to be able to work with someone for a while to get them to understand your philosophy of football."
Ferguson was famously said to be clinging on to his job in his fifth season in charge before Manchester United won the FA Cup in 1990 - and then went on to become the most decorated manager in Britain.
Rodgers has just completed his third season in charge at the club. It is accepted that his first season was more about implementing his own ideas and transition, while the side started to play more positively and delivered results in the second part of that campaign, which was then followed by a title challenge the next season.
The past season has evidently been a setback, and the defeat to Stoke has turned up the volume of discontent surrounding the manager. It's a bit premature to compare Rodgers to Ferguson, but maybe not so the scenario.
If Rodgers is safe for the next season, there is going to have to be a vast improvement in order for him to maintain his position in the medium term.
