Swansea City manager Garry Monk said Jonjo Shelvey deserved his call-up to the England squad after making a bright start to the Premier League season.
Shelvey was among the 22 players selected by Roy Hodgson on Sunday for next month s Euro 2016 qualifiers against San Marino and Switzerland.
The 23-year-old, who earned his one and only cap against San Marino in 2013, has hit the ground running this term after meeting with Monk at the end of 2014-15 to address his discipline and application.
Speaking to reporters following Sunday s 2-1 win at home to Manchester United, Monk lauded Shelvey for his efforts.
It s time to grow up and he s done that, Monk said.
I had a good relationship with Jonjo and worked closely with him and he s worked very hard.
He worked very hard at the end of last season and he s come back in a good way.
He s much fitter, he s looking stronger, he s not quite there yet, but he will be there if he continues to work and play like he is.
You forget how young he is, but it s time to grown up and he s doing that in a good way.
