Arsenal seemed to be in the best of position when they sold Cesc Fabregas to Barcelona in 2011. Not only the Gunners had the options of exercising his buy-back clause, but were entitled to receive a 50% transfer fee for the Spaniard, should Barcelona make any profit on selling the midfielder.

Chelsea now stand as the biggest problem for the Gunners. The Blues are on the verge of securing a deal for Fabregas. Arsenal had an option of matching that offer, but they chose not to enter into any bidding war.

The Blues are now planning to prepare the deal in such a way that would lead Arsenal to miss out on any payment for Fabregas. According to reports from The Telegraph, Chelsea are not keen to hand Arsenal any percentage of the transfer fee. Chelsea have lodged a formal bid for Fabregas and are hoping that progress could be made on a deal this week. 

Barcelona signed Fabregas on a complicated deal, where the Catalan club paid an initial £25.4 million, with the player contributing to the Gunners £880,000 each year of his contract.

Adding further clauses into the deal, it sums up to just over £28m. Barcelona are demanding £30m for the Spanish midfielder, but Chelsea ideally want to pay around £27m, which could see Arsenal missing out any payment over the deal.

Chelsea meanwhile are keen to announce the Diego Costa deal within this week. It also remains to be seen, how quickly they can wrap up a deal for Fabregas as well.
