International football was back in action this week as the Uefa Nations League kicked-off once again around Europe with the first round of matches since the outbreak of Covid-19. Cristiano Ronaldo reached yet another milestone in his extraordinary career when he <a href="https://www.thenational.ae/sport/football/cristiano-ronaldo-sets-sights-on-international-goals-record-after-reaching-century-for-portugal-in-pictures-1.1074942">broke the 100-goal barrier</a> as Portugal defeated Sweden 2-1. Gareth Southgate's England plans were thrown into disarray when he was forced to drop two players, Mason Greenwood and Phil Foden, from the squad after <a href="https://www.thenational.ae/sport/football/mason-greenwood-and-phil-foden-absent-from-england-training-after-breaching-covid-protocols-in-pictures-1.1074162">breaching Covid-19 protocols</a>, in between matches against <a href="https://www.thenational.ae/sport/football/raheem-sterling-spot-on-as-england-beat-iceland-in-nations-league-1.1073364">Iceland</a> and <a href="https://www.thenational.ae/sport/football/conor-coady-8-harry-kane-6-jadon-sancho-4-england-player-ratings-against-denmark-1.1074886">Denmark</a>. Both players <a href="https://www.thenational.ae/sport/football/mason-greenwood-i-apologise-to-gareth-southgate-for-letting-him-down-1.1074571">issued apologies</a>. There was controversy and apologies in the tennis world as well, after world No 1 Novak Djokovic was <a href="https://www.thenational.ae/sport/novak-djokovic-disqualified-from-us-open-after-hitting-line-judge-with-ball-1.1073815">disqualified from the US Open</a> after accidentally hitting a line judge in the throat with a ball. The Serbian became frustrated after suffering a fall and having dropped serve to trail 5-6, hitting a ball to the back of the court, striking a female line judge. The Tour de France continued into its second week and there was more success for UAE Team Emirates, when <a href="https://www.thenational.ae/sport/other-sport/uae-team-emirates-tadej-pogacar-grabs-first-stage-win-at-tour-de-france-1.1073799">Tadej Pogacar edged out fellow Slovenian Primoz Roglic</a> in a sprint finish to win Stage 8 – his first in the Tour.
