Shinji Kagawa was one of a handful of high-profile departures from Manchester United on deadline day.
The 25-year-old arrived at Old Trafford for a fee of around £17 million back in 2012, but he failed to live up to his billing.
He has now re-joined Borussia Dortmund for a fee of around £6 million - and his new team-mate Sebastien Kehl has revealed that the Japanese international felt a 'huge sense of relief" to have left Old Trafford after two unsuccessful seasons.
"You could see that it was a huge relief for Shinji Kagawa [to have left Manchester United for Dortmund]," the former Dortmund captain said.
It was also suggested that some of Van Gaal's public comments regarding Kagwa's future had forced him to leave the club and return to the Bundesliga.
"It was not an easy situation for him at Manchester in the past few weeks. And then there were some comments from his coach that prompted him to return to Dortmund. He gets a lot of faith here. Everything that he's been missing in the past few months, he'll get back here again."
Along with Kagawa, the likes of Danny Welbeck, Tom Cleverley, Javier Hernandez and Wilfried Zaha all left the club towards the end of the summer window, while six new faces arrived at Manchester United for a combined fee of around £150 million.
There's still plenty of transfer buzz about the Red Devils despite the transfer window being closed - and this morning's Express claims they could miss out on top January target Kevin Strootman to PSG.
Just hours after the summer window closed it was suggested that the Red Devils would target a move for Strooman once he had proven that he was over his knee injury. However Roma are now in the running, and their interest in youngster Adrien Rabiot - confirmed by boss Rudi Garcia this morning - could be used to negotiate a deal for Strooman in the new year.
Radamel Falcao, has been having his say on his late loan move - the Colombian says he is excited to get started after the international break, and admitted he feared that the knee injury that stopped him from featuring at the World Cup would wreck his career.
