Chelsea's last 25 signings : Pato, Pedro, Amelia, Baba Rahman, Begovic, Kenedy, Falcao, Hector, Miazga, Nathan, Djiloboji, Pantic, Cuadrado, Kante, Luiz, Alonso, Batshuayi, Eduardo, Bakayoko, Zappacosta, Drinkwater, Rudiger, Morata, Caballero, Barkley.
It went absolutely downhill after the 2014 summer window, when we signed Costa,Fabregas and Luis. Tbh from the list above - none of them were world class signings - from the point we signed them, yes some of them turned out to be a great signing, like Kante's one but apart from him can we really say the same thing about other players? Maybe Luiz? (can't say anything about Morata and rudi since its their first season). And our net spent in this season is probably around minus 30(including the Costa's fee).
Let's be honest our board is not showing enough ambitions like the other PL clubs atm.
