The scenario that could see Costa to Arsenal and Mourinho to United?

A reported development with Roman Abramovich at Chelsea could impact the transfer market, Arsenal and Manchester United.

According to recent transfer reports, Chelsea owner Roman Abramovich is desperate to sign Paris Saint Germain striker Edinson Cavani, even if it means having to convince manager Jose Mourinho not to purchase the Portuguese's primary choice of Atletico Madrid hit-man Diego Costa.

Diego Torres Romano, a Spanish reporter, seemingly has inside information that implies Abramovich is not sold on Costa and that "the Russian [Roman] wants Cavani."

If Abramovich was to engage Mourinho in this dialogue, would Jose feel like power was being taken away from him or that he was being undermined in the transfer market?

Mourinho, of course, will only be too aware of Abramovich's desire to sign players, perhaps reminding himself of Andriy Shevchenko… how the player flopped in the Premier League yet how the Ukrainian remained in the team-sheets before eventually casting the striker aside.

Cavani could be recruited in the summer at the expense of Costa and, if that were to occur, Mourinho may well look enviously toward the power London rival Arsene Wenger has at Arsenal and what Sir Alex Ferguson enjoyed at Manchester United - something the upper brass at Stretford could use to entice Jose to Old Trafford.

Cavani to Chelsea also has further ramifications in the English transfer market as it could leave Arsenal with a free run at Atletico star Costa.
