All the transfers for Sheffield Wednesday's League One promotion rivals as Ipswich Town flash the cash

The Owls snapped up Aden Flint on loan from Stoke City as their only signing in January, with the experienced centre back coming in as a direct replacement for Mark McGuinness after he was recalled by Cardiff City.

But while Darren Moore brought in only one fresh face, many of their rivals were getting busy with plenty of new arrivals – Ipswich Town especially so as they reportedly spent two seven-figure sums to bring in Nathan Broadhead and Harry Clarke among others.

Derby County were similar to Wednesday with a subdued window, while Bolton Wanderers are throwing the kitchen sink at their hopes of promotion by bringing in players from teams such as Manchester United, Manchester City and Southampton.
