Arsenal’s continued robust financial figures must be backed up by results on the pitch, according to the chair of the Arsenal Independent Supporters’ Association.

The Gunners’ parent company announced a profit of £24.7 million and a cash reserve of £193.1 million in the same week as Arsene Wenger’s side slumped to a disappointing 2-1 defeat in their opening Champions League tie away to Dinamo Zagreb.

The results, covering the year ended May 31, 2015, put the group’s total turnover at £344.5 million, up from £301.9 million in 2014.

Arsenal invested heavily in Arsene Wenger’s FA Cup-winning squad over the period, with an outlay of around £114 million and increased wages now up to just over £192 million. However, the Gunners added only goalkeeper Petr Cech, signed from Chelsea, to the squad during the 2015 summer transfer window, and they did not bring in another striker ahead of the September deadline despite a lengthy injury to Danny Welbeck.

Although Arsenal’s bumper cash reserves, which exclude a £35 million payment on the long-term Emirates Stadium financing, are intended to cover costs for a full season, and are not solely designated for player transfers, there are growing calls for some of the surplus funds to be used on recruitment.

AISA chair Lois Langton told Press Association Sport:

“Arsenal’s financial results at least show that the club has produced one good performance so far this week.

“There is little doubt that the club is well-run. What supporters want to see, however, is that the financial results are matched by results on the pitch – and it is unfortunate timing for Arsenal that the results have followed hot on the heels of a woeful performance in Europe.

“Spending money in the transfer window isn’t always the answer; one quality signing is often better than several average signings.

“However, in a week where many supporters have spent considerable money following the team into Europe only to see a below-par performance, the financial figures will only add fuel to the fire for those calling for further squad investment.”
