Colin Montgomerie has revealed he believes only four players are capable of winning this week's Open Championship.
The 49-year-old named Tiger Woods, Lee Westwood, Justin Rose and Paul Lawrie as the only competitors this week who have the all-round game to compete at Royal Lytham.
Montgomerie told BBC Radio 5 Live: "There are three technical systems they have got to have and they need all three to win.
"There's only a few that fall into every category. One of those four are going to win."
The former Ryder Cup captain has played in more than 500 European Tour events.
