David Moyes believes Sunderland's market work ultimately saw them relegated this season.
Moyes has signed 13 players since his arrival on Wearside but has noted that his squad in one of the most dependent on free transfers and loans in the Premier League's history.
He said: “If you look at what we have been able to bring in – there has been less this year, and that has obviously affected it.
You probably need to look back to the start of the season to see where we needed to make the recruitment better, but time was so short and that was where the difficulty was."
