Morgan Schneiderlin is looking forward to being reunited with Nigel Adkins at Old Trafford. The 26-year-old Frenchman played under Adkins during his time at Southampton and is eager to see his former boss when Adkins' Sheffield United face Schneiderlin's Manchester United in the FA Cup third round.

Schneiderlin spent just over two years working under Adkins, as the Saints achieved back-to-back promotions from League One into the Premiership.

"The standard is good in League One. You can see some teams in there like Sheffield United who are big teams," he told Manchester United's in-house TV station MUTV. "There are some quality players in the league and every team is playing for their lives; it's a league you need to take very seriously."

Schneiderlin – who moved to Manchester United last summer – also revealed he enjoyed working with Adkins, who was sacked by Southampton in January 2013.

"It will be great to see him. He was an important part in the Southampton rise. He came in when we were in League One and in his first year we went into the Championship and then the Premier League," the Manchester United star said.

"He didn't have enough time to show his skill as a Premier League manager with Southampton but it was a joy to work with him. He's a manager who is always optimistic and always has a smile on his face. It will be nice to see him."
