(CNN) -- World number five Andy Murray has parted company with coaching consultant Alex Corretja, as he looks to arrest a worrying slump in form this season.
The British number one has worked with Spaniard Corretja on a part-time basis for three years, helping the Scot to reach three grand slam finals and win six Masters Series events.
In a statement on his official website, Murray said: "I have had a really good relationship with Alex over the past three years.
"I have learned so much from being around him and I want to thank him for his hard work, enthusiasm, dedication and support.
"He has been a great friend as well as a mentor to me and we've shared lots of success and good times both on and off the court," Murray continued.
In reply, Corretja added: "Helping Andy has been a great experience for me, he's got great talent and can be one of the best on any surface."
Murray has seen a huge slump in his form since his defeat to Novak Djokovic in the Australian Open final in January -- losing early on at both Indian Wells and Miami to qualifiers.
The 23-year-old will now be seeking a new coach with former Czech great Ivan Lendl amongst the names being linked with the position.
