Liverpool playmaker Alex Oxlade-Chamberlain believes his positive mentality has been key to dealing with the devastating knee injury he sustained last campaign, which ruled him out of contention for England's World Cup squad.
The 24-year-old scored five goals and provided eight assists for Liverpool in his debut campaign at the club before sustaining a season-ending cruciate ligament rupture in the Champions League semifinal win over AS Roma.
The injury meant that Oxlade-Chamberlain missed his third major international tournament for England through injury, after the midfielder was ruled out of the 2014 World Cup and the 2016 European Championships.
"It's obviously been really tough to miss out at this time of the season ... I was really enjoying my football, so for it to all come crashing down in one moment, with one tackle, it's never great," Oxlade-Chamberlain told Liverpool's website.
"As a character I'm positive and I'm trying not to let myself get too down, obviously I've got a tough rehab ahead of me and moping around isn't going to get me through that!
"I must admit the first game against Tunisia was tough to watch -- it's a moment when you realise what a great opportunity you're missing, but these things happen in life and I'm keeping positive."
Chamberlain also admitted that he was "devastated" to miss the Champions League final in May, where Liverpool lost to holders Real Madrid, with the former Arsenal player seen in tears on the pitch after the defeat.
