Amo Racing spent 10.4 million guineas on nine horses during a two-hour spending spree at Book 1 of the Tattersalls October Yearling Sale on Tuesday.

Headed by 52-year-old football agent Kia Joorabchian, Amo Racing is a relatively new player in racing's premier league but has already won numerous big races, headed by King Of Steel, winner of the Champion Stakes at Ascot a year ago.

In partnership with Evangelos Marinakis, owner of Greek football team Olympiacos and Nottingham Forest, Amo Racing began its string of big-priced acquisitions at around 2pm on Tuesday when buying a Frankel filly for 4.4 million guineas.

From Newsells Park Stud, she is a daughter of Group 2 winner Aljazzi

After bloodstock agent Alex Elliott had seen off Japanese underbidder Mitsu Nakauchida for the filly, he said: "Phew! Kia and partners wanted the filly very badly – a Frankel filly from that family and with that physical, she was always going to be a collectors' item. It is a deep price tag and, though we had discussed her at length, obviously I did not see her making that – but we had very much honed in on her.

"But she is part of Team Amo now... wow! She is a spectacular filly, it is a spectacular price, a spectacular bunch of horses here. I'd like to say I was a cool customer when all that was taking place, but that would be a fib – I have never been in that rarified atmosphere before.

"She's out of an exceptional Shamardal mare, so she is bred on the same cross as Ylang Ylang, who won the Fillies' Mile. She will be trained by Ralph Beckett who already has Angelo Buonarotti and Cathedral for Amo Racing."

Beckett is also likely to train the Frankel full-sister to Alpinista which Amo bought for 2.5 million guineas. She was consigned by Staffordstown Stud, the Irish arm of owner-breeder Kirsten Rausing's Lanwades Stud in Newmarket.

Both fillies were auctioned by John O'Kelly of Tattersalls who had some fun with the Amo Racing team during the bidding on the top lot. Joorabchian had his back turned to the auctioneer the entire time while Elliott lodged the bids. When bidding stalled momentarily at 2.6 million guineas, O'Kelly implored the Amo Racing team to continue, singing "do that to me one more time" in the style of Britney Spears.

It looked like Amo Racing would lose out at 4.2 million guineas but when O'Kelly pleaded with Joorabchian to "to turn around and have one more go, for the heck of it", the winning bid of 4.4 million guineas was submitted.

Joorabchian said: "We need strong pedigree fillies, and we have a lot of horses going to stud in the next year, such as Bucanero Fuerte and King Of Steel, it will be this year or next year we will have to make a decision soon., and we have Persian Force already at stud. We need to back them, otherwise we are just going to get left behind – we have to back our stallions to have a chance of winning.

"It is very difficult to buy such mares because the likes of Juddmonte, Coolmores, Shadwells, all the big guys own all the big mares. So we have to come out here and hope that what we are buying in terms of pedigrees, will make us competitive.

"It is very hard to buy [such pedigrees] after yearling stage – once a filly has won a Group 1 you are in very high prices, so you have got to try and get them earlier and hope that they go on well."

Of Frankel he enthused: "Frankel has had huge success, and he just keeps on producing. You look at all the Frankels and what they are doing, these amazing mares and fillies, you just have to back him."

Amo Racing continued its spending shortly afterwards when paying 1.1 million guineas for a Frankel colt out of a winning sister to Midday from Baroda Stud. The colt is a half-brother to Group 3-placed Redress.

Before 4pm Amo Racing paid 675,000gns for the Siyouni own-sister to the dual champion colt St Mark's Basilica (and half-sister to 2000 Guineas winner Magna Grecia) from breeder Norelands Stud.

Sheikh Mohammed is at Park Paddocks this week and his Godolphin operation recorded its first purchase of the week when giving 2.2 million for a No Nay Never colt from Ballylinch Stud. The colt is a half-brother to 2023 Champagne Stakes winner Iberian.

Earlier on Tuesday bloodstock agent Richard Knight, acting for the bin Laden family's Salhia Stud, spent 925,000gns on the Dubawi filly out of the Prix de Mallerret winner Waldlied, sold by Newsells Park Stud.

"She is a filly I absolutely adored when I saw her and Newsells has a fantastic draft of horses, they have been so well prepared," said Knight. "She is a Dubawi filly from the family of Waldgeist, and is just a beautiful physical, a lovely strong filly.

"We are looking to build a racing band whom we will breed from at the end of the day, and she looks like the type of broodmare we will love to have. We are all delighted to get her – I don't know who will train her yet, we will make that decision at a later date."
