Stan Kroenke has seen his net worth rocket just days after Mikel Arteta was left empty-handed in the January transfer window. Last month, the Spaniard voiced his concern about Arsenal's lack of depth on numerous occasions following injuries to Gabriel Jesus and Bukayo Saka – but his desperate pleas for reinforcements fell on deaf ears.

Ironically, the North Londoners didn't make a move until it was too late; football.london understands Arsenal submitted a £40m proposal for Ollie Watkins, plus add-ons, just days before the deadline. Unsurprisingly Aston Villa rejected the low-ball offer, demanding £60m for the 29-year-old striker's signature.

It's understood that Watkins was keen on the idea of a move to the Emirates Stadium and, had the two Premier League clubs agreed on a deal, he would've made the switch. Unfortunately for Arteta, who was left disappointed, the Gunners fell short and they could soon be hamstrung in the title race.

"We had a clear intention which is always when a window opens to explore the opportunities to improve our squad with players that can make an impact," said the Arsenal boss on Wednesday. "With players injured, we've been impacted and we haven't achieved it.

"We are disappointed in that sense but, as well, we are very aware that we only want to bring certain kinds of players and we have to be very disciplined with that as well. I think that we were.

"It's in the profile, a player that we believe can make us much better. Financially there is a lot of ways, a lot of things that we must stay in the lane that has taken us this far and from there try to improve."

While the Arsenal board were scrapping together loose change to fund a bid for Watkins, the club's owner racked in 10-figures. According to Bloomberg, Stan Kroenke has recently seen his net worth go up 16.8 per cent (£1.72bn/$2.15bn), reaching an eye-watering $14.9bn (£12bn).

The 75-year-old also owns the Los Angeles Rams (American football) and the Denver Nuggets (basketball), as well as Colorado Avalanche (hockey) and Colorado Rapids (football). A $1.5bn (£1.2bn) liability was included to reflect the cost of acquiring these assets.

Bloomberg add that Ellen Moskowitz, a spokesperson for the Arsenal chief, didn't respond to emailed requests for comment on the net worth calculation. In the meantime, Josh Kroenke – Stan's son and co-chair at the Gunners – continues to be heavily scrutinised for ignoring Arteta's calls for help.
