Barnsley offer Everton, Wolves target Butterfield new terms
The Daily Star says Barnsley have offered to quadruple Butterfield's wages to keep him out of the clutches of the Premier League big-guns.
The Tykes' skipper's pay rise would swell his salary to £8,000-a-week.
Former Manchester United trainee Butterfield, 21, who is also wanted by Championship top-two Southampton and West Ham, is out of contract next summer and admits: "I'm still thinking my future through.
"I love playing for gaffer Keith Hill and Barnsley, but I have also got to consider what is best for me.
"I want to perform at the highest level and I have ambitions to play in the Champions League and for England."
