Brentford have signed goalkeeper David Button from Charlton for an undisclosed fee.
The former Tottenham trainee joins the Bees on a two-year deal less than 24 hours after Simon Moore left Griffin Park in favour of Premier League new boys Cardiff.
Brentford manager Uwe Rösler told the club's official website: "We always felt we had to have a Plan B in place in case we had offers for Simon Moore.
"Over the summer we had goalkeepers in on trial and we made lists and enquiries in case Simon left.
"That happened this week and with Simon going out the door, there is an opportunity for someone to come in.
"We decided David was the perfect choice for us. He is at the right age and he is very hungry to make the number one spot his own.
"As soon as Simon left, David was our first choice. He is the only player we enquired about and the only player we made a bid for."
