Netherlands goalkeeper Jasper Cillessen has confirmed he will join Barcelona from Ajax, announcing the move via Twitter.

Cillessen's move to the LaLiga champion is seen as a response to Manchester City's pending signing of Chile 'keeper Claudio Bravo. 

Ajax moved swiftly to replace Cillessen, announcing the signing of Newcastle United goalkeeper Tim Krul on a season-long loan.

Krul has also signed a one-year contract extension at St James' Park which will keep him on the club's books until 2018.
