The the same as Luton Town's Steven O'Leary, who is currently on loan at Rovers, Francis is 20 years old and struggling to break through into the first team at his Championship table topping employers.
Francis has played U-20 age level football for England, playing against Russia last season, when he also made 14 appearences for Sheffield United.
Sheffield United fan, Russ, told Tranmere Rovers mad that "Francis was a class act, until he got injured. Simon is very versatile. He can play left midfield, central midfield, right back and center back, or even, if need, right wing. I'd personally say his best position is right-back, and I'm looking forward to seeing him back to full fitness after his injury.
He's not the bravest defender, and his heading is not the best, which isn't great for a defender, but he does the job well, thats the important thing.
From what I can remember of him, his passing was good and he was good at running with the ball, but I can't remember his crossing too much!
Simon, who according to Brian Little is very versatile, will wear the number 2 shirt and will go straight into the squad for Rovers away game with Scunthorpe United in League One on Saturday.
