Lionel Messi says that his injured knee feels much better despite fearing the worst when he collided with the goalkeeper during a Champions League match against Benfica.

The Barcelona forward says he may miss Sunday's league match at Real Betis, but had originally thought his career might be in jeopardy.

Messi says "I sincerely thought it was the last ball I would be touching for a long time because of the pain. I tried to go ahead and shoot, but I didn't have the strength."

Messi is trying to equal a 40-year-old scoring record held by Gerd Muller. He has scored 84 goals in 2012 and has four games to catch Mueller, who scored 85.
