And if Scunthorpe, who beat Huddersfield 4-1 earlier this month, slip up at Doncaster then the Yorkshire side could go to the top of the table.
Taylor-Fletcher, who hit a brace in the 3-0 win over Oldham last weekend, said: "We've got a big test coming up against Brentford.
"But if we keep on playing like this and working for each other then we will stay at the top of the table."
