Lewis Hamilton is confident that his close friend Adrian Sutil will bounce back from the crushing disappointment of being taken out of fourth place in Monaco.

"Adrian's a really good friend of mine," said Lewis, who enjoyed some spirited races with Sutil when they were team-mates in Formula 3.

"He's very well known for having a very strong head on his shoulders, so I'm sure he will bounce back from that."

Hamilton believes that Sutil's strong Monaco run will be the turning point in his difficult year.

"He needs good showings like that," he said.

"I very much support him and hope that he continues the momentum he has now, and tries to improve."
