Premier League transfer spending this summer has risen by £60m from the same point last year.
The increase, to £360m from £300m in July 2013, means this transfer window is likely to surpass the record of £630m set last year, according to Deloitte's Sports Business Group.
"This summer transfer window has so far seen a higher level of spending than in any previous summer window," said Deloitte's consultant Alex Thorpe.
"It may well be a new record summer."

The transfer window, which officially begins at midnight on the final day of the season, has now been open for two months. It closes on 1 September.
This year's outlay so far also dwarfs the figures from other previous years. In 2012, spending stood at £190m at this point, while in 2012, it was £150m.
Last year Premier League clubs went on to spend £630m over the summer transfer window as a whole.
That figure includes the transfer deadline day signings of Marouane Fellaini to Manchester United for £27.5m and Mesut Ozil to Arsenal from Real Madrid for £42.4m.
New boys Burnley have been the busiest Premier League side, making seven signings so far, but the majority of those have been free transfers.
Premier League clubs have been bolstered by the record television deal with BT and BSkyB between 2013-14 and 2015-16, worth a total of £3.018bn.
"One of the main drivers of Premier League spending continues to be the increased resources clubs now have as a result of improved broadcast deals," said Thorpe.
"Last season the average Premier League club received around £25m more in central broadcast distributions than they did in 2012-13, which helped fuel the record transfer window last summer."
The top clubs are set to receive even more money when BT's £897m deal to broadcast Champions League games takes effect from 2015.
|Biggest signings by British clubs this summer|
|Diego Costa||Atletico Madrid||Chelsea||£32m|
|Ander Herrera||Athletic Bilbao||Manchester United||£29m|
|Luke Shaw||Southampton||Manchester United||£27m|
|Filipe Luis||Atletico Madrid||Chelsea||£15.8m|
|Enner Valencia||Pachuca||West Ham||£12m|
The transfer window so far has been dominated by big-money signings from foreign leagues. International signings have accounted for over 60% of incoming cash transfers, with eight of the 10 biggest transfers involving a player from a overseas club.
Gordon Taylor, chief executive of the Professional Footballers' Association, told BBC Sport he was troubled by the growing trend in international signings.
"What concerns us is that young English players aren't getting the chance to break through any more," he said. "The pattern is only going one way.
"It's no use Uefa having quotas for home-grown players in the squad - it needs to apply to the starting line-up. Otherwise I can't see the situation changing."
Despite the international emphasis of the summer's buys, the World Cup appears to have had only a moderate impact on spending, with just 12 of the 62 players signed so far on show in Brazil.
Ecuador's Enner Valencia, who completed a £12m move to West Ham, and the Netherlands' Daryl Janmaat, who joined Newcastle, were among the less-heralded names who impressed with their displays at the tournament.
