Tottenham Hotspur manager Mauricio Pochettino said the opening goal in Arsenal's 2-0 win over his team in the Premier League on Saturday should not have stood and it changed the dynamic of the game. Shkodran Mustafi gave the Gunners the lead by heading home from what replays showed was a slightly offside position in the 36th minute. The free kick that led to the goal was also controversial, with Davinson Sanchez being penalised by referee Mike Dean for a disputable foul on Alexis Sanchez, who went on to score the second five minutes later. Defeat by Arsenal means Pochettino has now won just once in 17 away games against the Gunners, Manchester City, Manchester United, Chelsea and Liverpool since taking over as Tottenham manager in 2014. Pochettino, however, denied there is a trend and said improving his side's away performances against top teams was not his highest priority. Danny Rose was left out of Tottenham's matchday squad against Arsenal despite being fit to play. Pochettino denied he had fallen out with the England full back and insisted he was easing him back into regular action following long-term injury.
