Deadline day in recent years has often felt more like a mopping-up operation than a frantic rush to land a big deal, but this year there is a sense that everyone is still on the lookout for a last-minute star arrival.
For Chelsea, their poor start to the season could lead them back into the market for another forward, especially if they sell Christian Pulisic or Hakim Ziyech, or both.
Manchester City meanwhile are now in talks for Borussia Dortmund defender Manuel Akanji, and Arsenal are reportedly still on the hunt for another midfielder.
Ad Manchester United and Barcelona could yet be the most active teams at the market's end. The Blaugrana face a race to hurry some of their players out the door, and United may need another striker should Cristiano Ronaldo depart.
