Joe Hart is not getting carried away with his current form and admits he could be the ‘ worst goalkeeper in the world again ’ by the next game . The 27-year-old put in a world class performance when Manchester City played Barcelona in the Champions League and pulled off a string of saves to keep his side in the game . Even though he was unable to prevent them being knocked out , the Barca players queued up to praise Hart afterwards . Joe Hart is refusing to get caught up in his own hype despite showing excellent form with his club of late . Manchester City goalkeeper Hart makes a save during training at St George 's Park with the England squad . Hart drew praise from Lionel Messi , Andres Iniesta and Luis Enrique despite City 's European exit . Lionel Messi said : ’ He was phenomenal , he stopped everything . We have to congratulate him on a great game because he 's a fantastic goalkeeper. ’ Andres Iniesta added : ‘ Hart was key to keeping them in it and was great in one-on-one situations . He was outstanding. ’ Barca head coach Luis Enrique also said : ‘ The score could have been a rout but Hart was incredible. ’ It is in stark contrast to the beginning of the season when Hart was dropped by City manager Manuel Pellegrini and replaced by Willy Caballero , but he has fought his way back . ‘ I have always been aware that for all the good stuff , I could be the worst keeper in the world again in one game ’ s time , ’ Hart said . ‘ I don ’ t get too wrapped up in good stuff or bad stuff . I just focus on my game and keep working hard. ’ The English keeper says that 'for all the good stuff ' that he showed in Barcelona , his form could easily dip . Messi tries to find a way past Hart but despite a dominant performance Barca were restricted to a single goal . Neymar attempts to nip the ball away from Hart 's clutches at the Nou Camp but again is denied . Hart will reach a half-century of caps if he plays against Lithuania and Italy in England ’ s next two games . To put that into context , Peter Shilton , England ’ s record cap holder with 125 , was 31 years old by the time he reached that landmark . Hart added : ’ I am honoured to play every single game I have done for England and for it to be 48 so far is fantastic but I just want to keep playing . There are plenty of other English goalkeepers who want to do the same and I am fully aware of that . I have got a lot of hard work to do to keep my place and I am willing to do that. ’ Will Caballero took over the City No 1 spot from Hart briefly for a spell earlier this season at the Etihad . Peter Shilton was 31 when he won his 50th England cap , while Hart could win his against Italy next week .
Willy Caballero produced a man-of-the-match display against Barcelona last week . But the England goalkeeper is not getting carried away with his good form . Hart was dropped for Joe Hart at Manchester City earlier this season . Goalkeeper is two caps away from 50 and says landmark will be an honour .
