Southend have completed the permanent signing of Grays Athletic striker Fredy Eastwood after a successful loan spell.
Tilson is delighted with the capture of Eastwood
Eastwood has agreed a three-year deal at Roots Hall after the two clubs agreed an undisclosed fee.
The 21-year-old, who started his career at West Ham, has scored six goals in his first five games for Southend.
"There's no question that he can score 20 goals or more if he carries on like he has," Blues boss Steve Tilson told his club's website.
