Above, we take a look inside the golf bag of four-time European Tour champion Marcel Siem.

The German won his first title at the 2004 Dunhill Championship but had to wait eight years before his next triumph – the 2012 Alstom Open de France.

He won the Trophee Hassan II the following year and came through a thrilling play-off at the 2014 BMW Masters to record his fourth European Tour title.
