Tottenham Hotspur were defeated 2-1 in Anderlecht despite missing a host of chances on Thursday night.
Spurs had enough chances to win yet a lack of sharpness in front of goal proved their downfall, prompting defender Alderweireld to come out and urge his team-mates to be more clinical.
"If you get the chances you have to take them. In Europe, you don’t get many chances and that is a little thing we are missing at the moment," Alderweireld told reporters.
"We create chances in every game but our scoring isn’t at our best level so I think that is something we have to improve. It is a matter of form, we have the players who can score goals so it is maybe a little bit down to belief but I think it will come."
Lack of options
One of Tottenham’s biggest worries at present is the lack of alternatives to striker Harry Kane.
During the summer, it became evident Spurs were seeking an alternative but a new striker signing never materialised - and it has left the White Hart Lane outfit rather short.
Clinton Njie and Heung-Min Son are options but neither seem too comfortable in the centre-forward positions and are best placed either in wide areas or as a number 10 through the middle.
It leaves Kane short of genuine competition, a fact which could see the England international play far too many games and suffer burnout later in the campaign.
