Celtic penalty hero Kris Commons pays tribute to younger brother Spencer after Champions League glory When you're mid-table in the Championship, you just think you're a decent player, like most players in the Championship. Spencer is a sparky. He played football and was in the same Notts County side as Kelvin Wilson but he broke his ankle - and dislocated it at the same time - so that was him finished. I owe him a lot. People used to say to me, "Your kid's better than you" so when I play now I feel that I am doing it for both of us. He was only 16 when he [suffered the injury]. He was breaking into the first team at the time with Kelvin and the big man always said he was a top player, never pulled out of a tackle - and that was probably his downfall: he didn't pull out of that one and got his ankle snapped. That was him finished, done. He went from being a young kid breaking into the first team at Notts County to fixing light fittings. He wasn't at the game last night. He came up for the Barcelona game and travelled to Spain for the away leg but he was up at five in the morning working at the Co-op. He doesn't even play five-a-side now. He has very limited movement and it still causes him problems now. It was a nasty bit of work on his ankle. Scotland star Commons displayed nerves of steel to take the decisive spot-kick at Parkhead but confessed yesterday that he believed that qualification had already been achieved when he stepped up to convert the award. The significance of what he was about to do eluded him at the time, although there was a sense of relief yesterday that his shot, which struck the underside of the crossbar, had subsequently bounced on the right side of the line. "I had no idea that Barcelona were drawing," he said. We got the impression they were winning. All the crowd were cheering and we were looking around at each other thinking, "They must have scored." They were chanting Xavi or Messi or something so we thought they'd gone 1-0 up and might go on to get two or three and we would just have to hold out for a draw. "When I put the ball down I wasn't thinking, "This is to take us into the last 16," I was thinking, "Just put your foot through it, you've done it a million times in training, straight down the middle, nice and high away from his feet, we'll win 2-1 - and, hopefully, Barcelona will do us a favour." I suppose it's the sort of stuff you dream about as a boy. It's one thing to do it on a park or in training and another thing to do it in a game when there is something at stake. That's completely different but I just thought it was a normal penalty. "It was only when I was in the treatment room that someone said, "We're through: Barcelona drew 0-0." Oh my God! I'll take my mobile phone out on the pitch next time! Former Forest team-mate Wilson, the most improved Celtic player this season, took time to find his feet at the club but he has emerged as an automatic first choice for mentor Neil Lennon. After missing the opening qualifying round against HJK Helsinki the 27 year-old has been an ever-present during the club's European adventure. Having managed to prevent Lionel Messi from scoring at the Nou Camp, he would now love to be given the opportunity to similarly snuff out Robin van Persie and Wayne Rooney at Old Trafford when the draw for the round of 16 is made on Dec 20. "Now we're [through] we're not thinking that that's our achievement," he said. We've beaten Barcelona, the best team in the world, to get there so we're confident we can beat anyone here. I would like to draw a Premier League team and Manchester United are their only group winners so that would be nice. That's not just because some people thought I was crazy coming here in the first place but because United are one of the biggest clubs in the world and I've never had the chance to play against them. I don't think anyone expected us to beat Barcelona or to beat Spartak home and away - but we did. We don't go shouting it from the top of the rooftops but we've always been confident. We've quietly gone about our business and proved everyone wrong. Celtic's success will, inevitably, lead to richer clubs being linked with moves for the likes of Gary Hooper, Victor Wanyama and, of course, Lennon himself. Will people down south start to look at our manager now? Maybe so," said Wilson. Obviously, he's done a great job here because we're the first Scottish club to win 10 points in the Champions League so he's doing something right. I imagine there will be interest in our players as well but no one will want to leave - why would you want to leave now? We're in the last 16 and not many players get to compete in the Champions League, never mind reach this stage. We're all cup-tied for the competition anyway so I don't think anyone will go - I hope not, anyway. Hoops in the money Celtic have made nearly €30 million in guaranteed revenue from Uefa for their participation in the Champions League this season: Play-off participation €2.1m Group stage participation €5.3m Match fees €3.3m Projected market pool €11m Performance bonuses €3.5m Last 16 qualification bonus €3.5m Total to date €28.7m Celtic's victory over Spartak Moscow - and qualification for the last 16 of the Champions League - has provided Scottish football its best coefficient points return since 2007/08. That was the last time Celtic reached the knockout stages of European football's most lucrative competition. Celtic's progress will not give the Scots another Champions League place but it does keep the status quo.
