Red Bull Salzburg striker Samuel Tetteh steps up training to full fitness

Red Bull Salzsburg striker Samuel Tetteh is increasing the work in training to regain full fitness before the start of the season.

The 20-year-old has re-joined the Austrian champions for pre-season but yet to kick a ball.

He is yet to attain full fitness after undergoing surgery in February to correct a knee injury.

Tetteh scored 10 goals in his first 20 games for FC Liefering and was immediately promoted to the first team before the injury setback.
