Golf-Spieth will find it tough to match 2015 feats – McIlroy (Reuters)

Rory McIlroy has warned rival Jordan Spieth that “self-inflicted pressure” will make it difficult for the American to follow up his blockbuster 2015 season with an equally successful 2016 campaign. World number three McIlroy knows how tough it is to maintain peak form for a sustained spell. Spieth took over as world number one, producing a magnificent season as he captured the U.S. Masters and U.S. Open titles and came perilously close to winning the British Open and U.S. PGA Championship.
