Colombia’s old guard led them to a 3-1 win against World Cup debutants Uzbekistan, ensuring they did not commit the same mistake as fellow Group K side Portugal in underestimating their opponents.Towards the end of a first half in which Uzbekistan held firm, the deadlock was broken by a moment of magic from Colombia, with Luis Diaz sending forward a sumptuous pass which Daniel Munoz finished brilliantly with his right boot in the 41st minute.But the central Asian side did not give up and were rewarded with their first-ever tournament goal in the 60th minute after some bizarre decision-making from goalkeeper Camilo Vargas, whose attempted block of Eldor Shomurodov’s volley was headed home by Abbosbek Fayzullaev.Unfortunately for Uzbekistan, that moment was followed by a goalkeeping howler of their own at the other end, with Diaz’s shot trickling over the line five minutes later after a fumble from Utkir Yusupov.And substitute Jaminton Campaz put the gloss on the win for Colombia in the ninth minute of stoppage time, heading home from a fine Cucho Hernandez cross. That sealed a hugely significant three points for the South Americans after that Portugal slip-up against DR Congo.Here, Jack Lang, Felipe Cardenas, Phil Hay and Tim Spiers analyse the key talking points.Diaz’s starring roleDiaz was in tears during the national anthem, and he went after Uzbekistan like a man possessed. The Colombia shirt seems to tap into the soul of the players who wear it.Diaz had already hit a post and caused plenty of havoc before his assist, drifting inside and outside and keeping Uzbekistan guessing. If he wasn’t going to score the opener, you sensed he was going to create it.The Bayern Munich forward’s pass to Munoz was brilliant for three reasons. Firstly, he’s 35 yards out, making that sort of pass even more difficult to land than it would be anyway. Secondly, the angle facing him isn’t a simple one. But more than that, his reaction to Munoz’s run is blink-of-the-eye stuff: his feet reacting as quickly as his brain can think.The timing of Munoz’s run and Diaz’s ball make the move impossible for Uzbekistan to defend against. As for Munoz’s flying finish? Goal of the World Cup so far, against some very, very stiff competition.The effort from Diaz which settled the game in the second half wasn’t on that level — but it completed a masterclass of a performance from the former Liverpool winger.
