Exciting forward player Ravel Morrison is the latest addition to Chris Wilder's Premier League squad.
Following a trial period, the former Manchester United academy graduate has signed a one-year deal with an option for a longer stay with the Blades, having impressed boss Wilder and his coaching staff at Shirecliffe and during the squad's trip to Portugal, despite missing the victory over Real Betis with a minor injury.
"Ravel is an undoubted talent and we are delighted that we have put together a deal that suits all parties," said Wilder. "I've spoken to a number of people about him and it is clear that he has serious ability.
"We are getting a fantastic footballer with a tremendous pedigree and this is a great opportunity for Rav, we believe we can help him get back to the level he wants to be.
"He's done extremely well during his time with us and it was great to have him in Portugal. It wasn't about him coming and being on trial because we knew about his abilities. Taking him with us was basically getting to know him and what he's about, what makes him tick and how he integrates with the players. Trips like what we have been on are invaluable for that."
The 26-year-old, capped by England at various age groups right through to U21 level, made his senior debut for the Red Devils in the League Cup in October 2010, having turned professional on his 17th birthday.
Morrison starred at Old Trafford in the FA Youth Cup final against the Blades, scoring twice in the second leg before gaining more first-team experience in cup competitions under Six Alex Ferguson.
In January 2012, Morrison joined West Ham for an undisclosed fee, scoring three times in 18 appearances during his time at Upton Park, which also saw him loaned to Birmingham City, QPR and Cardiff City, whilst with the Hammers.
Having terminated his contract at West Ham early, Morrison made the switch to Italy, joining Lazio on a four-year deal in January 2015, before most recently representing Östersund in the Allsvenskan in Sweden last season.
Morrison is the fourth summer capture so far, joining Luke Freeman, Phil Jagielka and Callum Robinson in signing on at the Lane.
