Jose Mourinho reveals 2 Chelsea first-team additions in Ruben Loftus-Cheek and Isaiah Brown

Chelsea manager Jose Mourinho has confirmed academy duo Ruben Loftus-Cheek and Isaiah "Izzy" Brown have been promoted to the first-team squad on a permanent basis.

Loftus-Cheek, 19, made his first-team appearance during the Champions League 3-1 victory over Sporting Lisbon on Wednesday 10 December while he enjoyed his Premier League debut during the recent 1-1 draw against Manchester City.

The box-to-box midfielder, who has been at Stamford Bridge since his time in the Under-8s, was also on the bench during the victory over Aston Villa.

Meanwhile, Brown joined Chelsea from West Bromwich Albion in the summer of 2013 after becoming the second youngest player ever to play in the Premier League following his first-team debut with the Baggies.

The versatile 18-year-old forward is yet to make his first-team start but was in the matchday squad during the game against City.

Mourinho has confirmed both younsgters have been made permanent members of the first-team squad.

'It's a decision we made. It's a way to find conditions to pay some high salaries, when you have four or five young boys coming from the Academy who in the beginning you obviously pay lower than that," Mourinho said, according to Chelsea's official website.

'It's also to try to give them a chance. In this moment, we have on the bench [Andreas] Christensen, Ake, Loftus-Cheek. Even if they're not playing – because the moment hasn't arrived for them to play a lot yet – to train with the first team, to be on the bench, to feel the pressure of a big game, all this is important for their development."

The Chelsea manager has suggested the two players are not ready to play regularly for the first team but believes they can develop into crucial members of the squad in the near future.

'It's about the potential of the players and it's about opportunities. It doesn't have to be about confidence or age; it has to be about talent. Kurt Zouma is 20 and he played against Liverpool and Man City and we had no problems with that," he said.

"I know it was a couple of minutes but Loftus-Cheek made his Premier League debut against Man City. It's our idea to think about the future, and when I come to a club with four years' contract it means that I am not going to stay for four months. I have to try to anticipate what is normal – players getting older, preparing the kids for the future.

"But I also know Chelsea's nature is to win, or at least to fight to win, so it's more difficult to do that in the team with the profile we have."

Meanwhile, Sheffield Wednesday have confirmed the Blues have recalled Lewis Baker from his loan spell at the Championship club even though he only joined the Owls on loan until the end of the season in January.
