Manchester City goalkeeper Zack Steffen underwent a medical at Championship side Middlesbrough yesterday ahead of a season-long loan, according to Daily Mail.

The USA international goalkeeper is joining Middlesbrough on loan to secure regular football ahead of the World Cup later this year.

Steffen has spent the last two seasons as understudy to Brazilian goalkeeper Ederson at City, and he has only played twice in the Premier League since his arrival in 2019. 

He has made 21 appearances in total for Manchester City since joining the club, 16 of those coming in the FA Cup and Carabao Cups.

Steffen joined Manchester City from MLS side Colombus Crew for £6.1million in 2019.

Manchester City have already signed a replacement for Steffen, ahead of his loan move to Middlesbrough. The Premier League champions have already signed 29 year old goalkeeper Stefan Ortega.

Meanwhile, Man City midfielder Kevin De Bruyne is now the longest-serving player at the club following the departure of Fernandinho and then Raheem Sterling.

De Bruyne has spent 6 years, 10 months and 15 days at Man City since joining from German club Wolfsburg in the summer of 2015.

The 31 year old midfielder has become one of the world’s best midfielders during his time at Man City and have won four Premier League titles.
