Miazga, who turns 21 next month, joined Chelsea from the New York Red Bulls in the January transfer window for around £3.5 million after establishing himself as one of the top prospects in MLS and went on to make two Premier League starts for the Blues over the second half of the season.
The US international centre-back showed well on his debut, a 4-0 win at Aston Villa in April, but noticeably struggled on his second appearance at Swansea City the following weekend, when he was taken off at half-time as the club fell to a 1-0 loss.
Interim manager Guus Hiddink decided against using the two-time capped defender again for the rest of the campaign, but Begovic was still impressed by how he handled the step up to Premier League football and is predicting a big future for him in west London after seeing his improvement on the training ground.
Asked in a Facebook Q&A about how he felt Miazga has handled the move across the Atlantic so far, the Bosnian told the Men in Blazers: “He’s at a great club in good hands and gets looked after really well, so we don’t have to worry about him too much.
“He fitted in well. He had his initiation, so he sang his song which helped him settle in well right away. I don’t know if I should be sharing, but he sang a Justin Bieber song!
“He’s a nice guy and obviously a very talented player. He’s still very young but he’s settled in really well. He’s already had some minutes in the Premier League which was a good experience for him and he’ll definitely be ready to kick on starting next season.”
Despite getting a brief taste of first-team action last season, what the immediate future now holds for Miazga at Chelsea under incoming manager Antonio Conte remains to be seen.
Playing time will obviously be hard to come by next season with John Terry now staying at the club and Conte expected to bring in defensive reinforcements over the summer, leading most to assume that the 6ft 3in stopper will be shipped out on loan.
At this stage, though, the New Jersey native expects to be given the opportunity to fight for a place in the senior squad when he returns for pre-season training next month.
“I’m not really focused on [a potential loan] right now,” Miazga told MLSSoccer.com last month while training with the US national team. “I’m just focused on the national team and when the Premier League starts again and the season starts up, that’s something we obviously have to discuss.
“It’s been a good learning process, going to a big club and learning the ways over there and adjusting to the Premier League and how they play their football. Obviously you go through your ups and your downs, which is normal, but it felt like I learned a lot.”
