Conor Gallagher's girlfriend Aine May Kennedy has shared her excitement for a 'new adventure' after jetting into Madrid with the former Chelsea star.
Gallagher completed a protracted £34million move from Chelsea to Atletico Madrid last week.
The England international made his Atletico debut on Sunday night, playing the final 30 minutes of their 3-0 win over Girona in the first match of the LaLiga season.
Following his home debut at the Metropolitano on Sunday, Gallagher briefly returned to London as he continues the transition to life in Spain.
His model girlfriend Kennedy shared a photo with the star on Monday night, as the couple boarded a flight to Madrid with their dog Freddy.

'Gallagher came on with a lot of energy,' Simeone said.
'That's what we'll get from him. He needs a bit of time to get used to opponents and to his team-mates.
With his enthusiasm and passion, we have to help him so that adrenaline is positive for the team.'
The midfielder had been training on his own at Chelsea after being exiled for the first-team set-up ahead of the transfer.
Gallagher had agreed personal terms with the Spanish club weeks ago, but the deal fell into limbo after Chelsea ended their pursuit of Samu Omorodion, who later joined Porto.
Atletico revived the Gallagher deal, with the Chelsea academy product leaving the club last week.

Gallagher, who captained Chelsea several times last season, had maintained his 'dreams came true' at the club despite being forced out by the Blues this summer.
'To everyone at Chelsea, thank you for making my dreams come true,' Gallagher said last week. 'It’s been an absolute honor every time I put on the shirt, and it was a dream come true to captain the team on many occasions. I loved every moment.
'These memories will last forever. I appreciate all the love and support from the fans. Hearing the chant of my name at the Bridge is a special feeling, and the banner you displayed meant the world to me.
'Thank you for everything. I wish the club all the best for the future, and I hope to see you all soon at Stamford Bridge!'
