LIVERPOOL: Chelsea goalkeeper Emi Martinez suffered a concussion after his collision with Everton's Jarrad Branthwaite and was taken to hospital for "precautionary tests", manager Xabi Alonso said after their 2-0 Premier League victory.

Pedro Neto's double at the Hill Dickinson Stadium ended Everton's unbeaten start to the league season but Chelsea's victory was overshadowed by the lengthy injury stoppage in the second half.

Martinez and Branthwaite came together when Everton's Kiernan Dewsbury-Hall whipped a free kick into the box and although the defender was back on his feet after treatment, the Argentina goalkeeper required treatment from paramedics.

The 34-year-old was eventually strapped to a stretcher and carried off the field before being taken to hospital.
