Sunderland fans have taken to social networking site Twitter to have their say on the signing of Jan Kirchhoff from Bayern Munich.
The Black Cats have recruited the central defender from German giants Bayern on an 18-month contract.
Kirchhoff joined Bayern in the summer of 2013, but he failed to establish himself in the first team.
During his time at the Allianz Arena, the 25-year-old had a loan spell at Bundesliga outfit Schalke in the 2013-14 season.
Sunderland are struggling defensively, and it seems that manager Sam Allardyce has signed the former Germany Under-21 international in order to strengthen it.
The Black Cats are in real danger of getting relegated to the Championship at the end of the season and currently find themselves second from bottom in the Premier League table.

Had no idea the Kirchhoff signing was actually confirmed. Welcome to #SAFC hopefully you can put your injuries behind you.— Peter Crumb (@MrPeterCrumb) January 8, 2016
