Theo Robinson scored twice in four minutes to help Southend United defeat his former club Millwall in a preseason friendly at Roots Hall.

The Lions led through a rather fortuitous goal shortly after half-time before substitute Robinson found the net on 76 and 80 minutes.

Millwall, who had defeated Gillingham 2-1 before heading to Essex for the midweek clash, take on Spanish outfit Real Sociedad this weekend.

Neil Harris made eight changes to the side that beat the Gills on Sunday, granting a start to Tom Bradshaw, who missed the last two fixtures with a tight hamstring, and Jon Dadi Bodvarrson his full debut.

The Shrimpers grew in confidence after an edgy opening first quarter, and it was no surprise that Southend conjured the first meaningful attack after Millwall continued to be sloppy in possession.

Stephen Henderson’s spectacular attempt, when he tried to acrobatically turn in Brandon Goodship’s cross, set the tone on 17 minutes.

Goodship was involved again when he fizzed a ball into the path of the advancing Dru Yearwood, only for Murray Wallace to thwart the danger.

The visitors had a chance before the break when Bradshaw shanked a drilled effort wide of the post, though they would lead shortly after half-time.

Former Charlton defender Harry Lennon’s attempted clearance ricocheted off Nathan Ralph, hit the underside of the bar and went in on 48 minutes.

After the freak goal, Millwall became more settled in possession but Southend fought back to level the scores.

Mark Milligan marauded forwarded from the back in search of the equaliser and saw his powerful 30-yard effort fly over goalkeeper Ryan Sandford’s crossbar.

Soon after, Southend came close again when Humphrys tested Millwall with a half-volley.

However, Humphrys’ replacement would have an instant impact. The former Lions striker swept home on 76 minutes to level the scores.

His second would arrive on 80 minutes when he nodded home Goodship’s delivery from a corner.

Tyler Burey, Billy Smith and Matt Smith were brought on during the second half but none of them made a real impact on the game.
