Chelsea boss Jose Mourinho has admitted that he has several transfer regrets over the course of his management career.
As part of the #AskJose Yahoo Sports Twitter Takeover, the Chelsea manager answered a number of questions on several different topics, ranging from his favourite cheese to his dream Chelsea signing.
So when asked if he has ever regretted not signing a player in his managerial career, he said: "Of course, many times. This is normal."
Somewhat frustratingly, Mourinho failed to expand upon this answer so we're left wondering who he could be referring to.
In the past Mourinho has managed Porto, Inter Milan and Real Madrid, as well as two stints at Stamford Bridge. As he's been in charge of some of the biggest clubs in European football, his teams have been linked with some of the best players in the world.
But more often than not, he snaps up who he wants. At the moment, the top Chelsea target is reportedly Atletico Madrid striker Diego Costa.
The Spain international is one of the most in-demand forwards in European football, and is set to lead the line for his country at the World Cup this summer.
Chelsea thought they had a £32m deal in place to bring Costa to Stamford Bridge, but the latest reports claim Atletico will now demand Romelu Lukaku in return for the Spaniard.
