Murray will take his time before choosing another full-time coach

Murray told BBC Radio Five Live: "With some important events coming up, I don't want to make a mistake and bring someone in quickly and have problems.

"I'm going to take my time, see who's available and make the right decision."

The teenager's first match without Petchey by his side is on Tuesday when he faces France's Jean-Rene Lisnard at the Monte Carlo Masters.

Murray employed Petchey as his full-time coach last summer after his impressive debut at Wimbledon, where he reached the third round.

But continued "disagreements" caused the British number one to initiate the split and he is now considering many factors before deciding who to bring in.

"Some players and coaches have a very professional relationship," Murray said. "They don't go out for dinner every night or stay in the same hotel rooms.

I apologise for showing my emotions and from now it's one of those things I'm going to have to keep in check Andy Murray apologises for his outburst at the umpire in the Davis Cup

"It's about finding the right person for my tennis and I'm confident I will make the right decision."

In a further attempt to wipe the slate clean, Murray has also apologised for his outburst at last week's Davis Cup tie.

Television microphones picked up the Scot swearing at the umpire during and after his doubles rubber with Greg Rusedski.

The incident ended up costing Great Britain $2,500 (�1,434) in the shape of a fine.

Britain fined for Murray outburst

Murray said: "I didn't intend to offend anyone when I said what I did to the umpire.

"I apologise for showing my emotions and from now it's one of those things I'm going to have to keep in check and I'm sure it won't happen again."

When Murray steps out on to the court in Monte Carlo on Tuesday he will be fully focused on his tennis.

"It's my first match on clay in nearly seven months," said the Scot.

"After the couple of weeks I had after Miami, then twisting my ankle, a throat infection and stopping with Mark, I want to just get out there and enjoy my tennis."
