Berlin - Schalke's new coach Roberto Di Matteo said Wednesday his priority is to improve the Royal Blues' defence as he prepares for a Champions League showdown with his ex-club Chelsea.
The 44-year-old was officially unveiled in Gelsenkirchen as Schalke's coach with his new team 11th in the German league and low on confidence after just two wins in their last 10 games.
The Swiss-born Italian will take charge of his first training session on Thursday and his first match as coach is at home to Hertha Berlin on October 18.

"It's a good team, which has a lot of potential going forward, but it has some problems in defence," said Di Matteo, who has replaced fired predecessor Jens Keller.
"We have to work on our defensive organisation and I have a lot of work ahead of me."
But there will be plenty of attention on his showdown against his former club in Gelsenkirchen on November 25 after Di Matteo steered Chelsea to the European title in 2012, but the former Azzurri star did not want to be drawn.
"I have only been here 24 hours and there are a lot of games to come before that one," said the ex-Lazio star with Schalke second to Chelsea in Group G after drawing their first two European games.
