Former Premier League striker Charlie Austin believes Tottenham's current form is "alarming", particularly when bringing the length of Roberto de Zerbi's tenure and the club's transfer window spending into the equation. Tottenham have only won three of their past 23 league games on home soil, with the latest sucker punch coming in Sunday's 2-0 defeat by Newcastle United. "They have been in the exact same position in the Premier League for the past two seasons," Austin said on BBC Radio 5 Live's Football Daily podcast.
