Marcos Alonso has hinted he may consider a move away from Chelsea this summer amid reported interest from his former club Real Madrid.
The Spanish wing-back, 28, only signed a new five-year contract at Stamford Bridge last October but has struggled for form under coach Maurizio Sarri.
Reports in Spain have linked him with a return to Real, the club where he came through the youth ranks before signing for Bolton Wanderers in 2010.
Alonso will hope to play a role when Chelsea play Arsenal in the final of the UEFA Europa League in Baku on Wednesday.
Asked by the Evening Standard if he was happy at Chelsea in light of Real's interest, Alonso said: 'I am very happy here but we will see what happens this summer.
'There is always talk [like this]. Is it a compliment? Yes. It means I'm doing well if other teams are trying to get in touch.
'But first of all I'm focusing on the final. I am very happy to have four more years here and hopefully I will stay many more years here.'
Alonso was an important part of Antonio Conte's Chelsea team that won the Premier League in 2016-17, performing well as a left wing-back.
But since Sarri changed Chelsea's formation to a 4-3-3 this season, Alonso has been deployed as an orthodox left-back.
And he was left on the bench for both legs of Chelsea's Europa League semi-final against Eintracht Frankfurt, with Emerson preferred instead.
Alonso said: 'For me personally, the path changed. I started very well, then the manager wanted different things from me.
'After that I was trying to do what he wanted and then he told me he wanted to play like I was at the beginning of the season. So maybe that has conditioned a little bit the way of my game.
'Has the criticism from the fans affected me? No. Football is like this.'
