Chelsea Manager, Mourinho Prefers Atletico Madrid's Koke to fc Barcelona's Cesc Fabregas!

Chelsea fc's coach, José Mourinho prefers Atlético Madrid’s Koke to out-of-favour Barcelona 27-year-old midfielder, Cesc Fabregas (former Arsenal captain). He's being offered for £30m. 

Though, Chelsea hierarchy have presented the Spaniard to Mourinho as an ideal goal-scoring midfield successor to Frank Lampard, who is leaving,  Mourinho, however, is unsure about the Spaniard, preferring instead to target Koke.
Would Koke sign for Chelsea? Or would he opt for Barça who are favourites to do so.
