(Reuters) - Liverpool striker Daniel Sturridge is optimistic of returning from injury for the key clash against former team mates and title rivals Chelsea at Anfield on Sunday in a boost for the Premier League leaders. "Hopefully this weekend I'll be back," the league's second top scorer, with 20 goals to team mate Luis Suarez's 30, told children in a question and answer session at a sponsor event for the club. "I'm not too sure if he'll play me or not," he added when asked whether manager Brendan Rodgers was likely to select him. "We'll have to see." Liverpool, chasing their first league title since 1990, have won their last 11 matches and are five points clear of second placed Chelsea with four games remaining.
