Spotted: what Van Dijk did at penalty spot before Alisson's save on Bowen

One of the biggest moments of Liverpool's 1-0 win over West Ham was Alisson's save to deny Jarrod Bowen from the spot.

Before the West Ham winger took the shot, however, cameras picked up Virgil van Dijk doing something sneaky at the penalty spot.

Clearly, it's not obvious that Van Dijk's actions impacted Bowen's penalty attempt. It was Alisson's brilliant save rather than a poor shot by the England international.

Still, it's notable that the Reds keep pursuing those marginal gains when it comes to penalties at either end of the pitch.
