Tottenham clinched a narrow 1-0 victory over bitter rivals Arsenal in a pre-season friendly on Thursday. Scorers: Sarr 45'The North London clubs battled it out at Kai Tak Sports Park as preparations

The Spurs midfielder scored the game’s only goal in the 45th minute, spotting David Raya off his line and lobbing him from a long, long way out. There was a decent tempo to the game in the first half but both sides lost their rhythm a little in the second.
