Barcelona defender Marc Bartra has insisted that he is ready to play for his side against Bayern Munich in the Champions League on Tuesday.

The 22-year-old says that he could slot into central defence in place of the injured duo Carles Puyol and Javier Mascherano for the first leg of their semi-final tie at the Allianz Arena in Munich.

"I'm really ambitious and a UEFA Champions League semi-final represents an incredible challenge," UEFA.com quotes him as saying.

"If [the coach] trusts in me, I believe I won't let him down. The more difficult a situation looks the more eager I am [to do well].

"Competing and training alongside the best players in the world helps you to grow and when you are chosen to play, you feel their positivity; it's contagious."

The second leg will be held at Camp Nou next week.
