Yossi tells Chelsea fans: Give Grant time
He said: "He is a good manager.
"But you have to be patient, give him a couple of months to prove himself, and if it's not good, then you can criticise.
"It's only the start for him. I know they drew (yesterday), which is not a good result for them.
"But I know Avram is a big manager, I believe in him and I am sure he will be successful there.
"He likes to play good, attacking football, and with Israel we achieved some great results.
"I am sure Chelsea will play better with him, just give him time."
