Boris Becker believes Djokovic's preparations for the Australian Open have taken a big hit

Following the immigration controversy which led to him being detained in Melbourne for a few days, Novak Djokovic may not have had enough time to adequately prepare for the Australian Open, according to tennis legend Boris Becker.

Djokovic arrived in Australia last week after being granted a medical exemption, but was detained upon arrival at the border due to a visa mix-up. The World No.1 was detained in an immigration hotel for a few days while the issue was being handled, but has since been released as the situation appears to be resolved.

Nonetheless, Becker has been one of the many to defend Djokovic from criticism. However, the German believes the defending champion may have angered the Australian people and could be in for a rowdy reception when he takes to the courts at Melbourne Park.

“I’m sure there will be a couple of boos and whistles, but he’s used to that," admitted Becker. "He was always a street-fighter who had to fight the odds and win over the crowd, and it was fascinating in last year’s US Open final when they finally embraced him.

“The crowd will be difficult with him but with each match he starts, he will win the crowd and they will embrace him again. But he is going to have a difficult first week.”

Furthermore, the six-time Grand Slam champion believes Djokovic's preparations for the first Major of the year have been hampered. Regardless, he still believes the Serbian will display the fighting spirit that has seen him win a record-tying 20 Grand Slams.

“He’s a remarkable young man, his spirits are better," added Becker. "He went to train at midnight [on Monday], that’s just who he is. He’s a different cat. He sees the world with a different pair of eyes.

“You may not agree with everything he does, but you have to respect him. And obviously his preparation is beyond bad. I don’t think he’s ever been in a worse position entering the week before a Grand Slam, but that’s just the way it is."
