Aston Villa have signed right-back James Bree from Championship rivals Barnsley and FC Basel midfielder Birkir Bjarnason.
"It's a very big club. I am now looking forward to getting out on to the pitch and helping the team," Bjarnason told Villa's club website.
Bree said: "(Manager) Steve Bruce was a big factor in my decision, when I met him I knew it was the right move for me."
