If the club decide to send the players on loan for their development it is because these players are not ready to play for Chelsea.
It is no secret that Chelsea have had a torrid time in this summer's transfer market and the Blues boss will hope to add to his squad before the window shuts on August 31.
Conte said: "It's simple".
Chelsea agreed to release Costa in a £76 million deal to the Chinese Super League club Tianjin Quanjian in January, but the move fell through due to a rule change by the authorities in China, who instituted a 100 per cent tax on all foreign transfers over $6.63 million to curb excessive spending by clubs.
"When he was already with the Spain national team [for a friendly against Colombia last June] and before travelling to Brazil to enjoy his holidays, he was released from Chelsea by SMS by the coach Antonio Conte". My aim is to try to improve my players, to try to improve my team.
"My only task is to focus on the pitch, what happens on the pitch, during the training session to work with my players". As you know the Premier League is the main target.
"We played against a very good side".

Rafael Nadal Stunned by 18-Year-Old Denis Shapovalov at Rogers Cup
Nadal, a three-time champion in Canada, took 71 minutes to beat 20-year-old Croat Coric, facing just one break point in the match. With him being a young star, it will be interesting to see where this takes him for the rest of the tournament and beyond.
Arsenal To Make Alexis Sanchez Premier League's Highest-paid Player
Arsenal have been relatively quiet on the transfer front this summer, although the business they have done looks shrewd enough. There was a lifeline for Wenger before halftime when Welbeck met Sead Kolasinac's cross to tap in an equalizer.
"Antonio Conte has to go through those two first before he gets to Roman Abramovich and that's where the problem lies".
One of the issues is that striker Diego Costa, last season's top scorer, remains in exile.
Conte was asked when Costa might return to Chelsea.
Chelsea then said that there's "nothing to report [on Diego Costa]" before explaining the situation when the cameras were switched off. Costa's situation is not thought to be a distraction with the Blues insisting that they have moved on, at least from a footballing perspective.
Pedro Rodriguez is also unavailable for selection after failing to recover from an ankle knock picked up in Sunday's Community Shield defeat against Arsenal, while Loic Remy is not in Conte's plans and Kenedy and Lewis Baker are expected to leave Stamford Bridge on loan in the coming days.
Victor Moses is suspended following his dismissal in last seasons FA Cup final while Bakayoko isn't available to make his debut as he's still working his way back to fitness from a knee injury.
