Opinion: Key Portsmouth, Ipswich, Charlton and Sheffield Wednesday signings ranked the best in League One to date

This summer’s League One transfer window has proven to be one of wildest and most unpredictable in recent memory.

Teams with varying budgets have been splashing the cash and working round the clock to get their teams ready for the new season.

As it stands, this League One campaign looks to be more competitive than ever, with some pre-season promotion favourites – Ipswich Town and Charlton Athletic to name a few – already dropping points.

It’ll take time for teams to gel and players to get used to their new surroundings, but some of the best transfers on this list have already hit the ground running and shown their worth.

But it isn’t just about this season, successful transfers can change the entire trajectory of a football club for years to come.

Considering the value of the player, their pedigree, how they’ve performed so far and their potential, here are the most impressive signings in League One so far.
