Celtic have given contract extensions to teenage twins Filip and Patrik Twardzik.

Filip, who has impressed for Neil Lennon's team this season in midfield prior to sustaining a groin injury, has committed his future until 2015.

Fellow midfielder Patrik, who has been a regular goal scorer for the Celtic U19s in recent seasons, has signed a one-year extension, tying him to the club until the end of next season.

The 19-year-olds from the Czech Republic first arrived at Celtic Park in 2009.

"We have learnt a lot since we have been here," Filip said. "The physical side changed a lot, but we are still the same players we have always been, our bodies have just progressed.

"I want to stay in the first-team and hopefully win some more medals this year."

Patrik has set his sights on following his brother into the first team. He said: "I have always dreamt about being the best player in every age group so I want to get there.

"Filip is closer to it than me but I will get there."
