One Direction have learnt to ''deal'' with the ''big changes'' they've faced.

The 'No Control' hitmakers - Harry Styles, Liam Payne, Niall Horan and Louis Tomlinson - have had a tough time of late with the shock exit of their bandmate Zayn Malik, and though they often feel ''huge pressure'', they are ''stronger than ever''.

Liam explained to America's Teen Vogue magazine: ''Mentally, more than anything, we've grown up--although we are still very immature. We're learning to deal with different things that attack us every day. Being in this position, there's obviously huge pressure all the time. There's been a lot of big changes in the band, and we have to grow past those different obstacles. To be honest with you, we're stronger than ever, which is amazing.''

One new track from the group's forthcoming new album is named after a girl, and though it doesn't feature Liam's girlfriend Sophia Smith, he insisted she doesn't mind being snubbed.

He said: ''I was listening to it with Sophia this morning, actually. One of songs has a different girl's name in the title, but it's fine--she didn't take any offense. We're just ready to go with it. It's going to be ace, I promise you that.''

And the 'Steal My Girl' hitmaker has promised fans will enjoy the new record.

Liam added: ''It's just pure greatness. I don't mean to sound arrogant when I say that, but it's just my favourite stuff we've ever done.''
