The Swedish tactician was one of the many managers who took a late dip into the transfer market as he successfully made a move for Everton's Jermaine Beckford for £2.5 million.
Eriksson told The Leicester Mercury: "You do wonder at times if it is right to have a window. It was easier when it was open all the time and perhaps fairer for the players,
"I am sure much of the business being done on the last day is a little bit desperate and that is not right. I think it was better before, but then I am old!"
Even though the former England boss did manage to secure a deal for Beckford less than an hour before the deadline, he was reported to have failed with moves for Rangers’ Nikica Jelavic and Bristol City’s Nicky Maynard.
This is not the first time that the Swede has questioned the structure of the English leagues, as he has been vocal in backing a winter break during the season.
