Both John Cofie and Nick Blackman believe that their strike-partnership is blossoming.
Cofie scored the opener at Colchester on Saturday, four days after Blackman netted at Coventry.
"Nick is a few years older than me and we're still learning about each other," said Cofie. "I like to feed information off him and we talk a lot.
"We knew each other before we came to Bramall Lane because we are both signed to the same agency. Every pre-season they provide a personal trainer to keep our fitness levels high so we have spent time with each other off the pitch."
Blackman adds: "We're working really well and hopefully it will continue.
"We're both quick players, defenders are very wary of our speed and they try not to give us a lot of time and space, but if we get the right service and we make the right runs they won't be able to stop us."
Cofie was Danny Wilson's first signing of the summer, agreeing a year-long loan from Manchester United, whilst Blackman joined the Blades on the eve of the new season after an undisclosed fee was agreed with Blackburn Rovers.
