The c has been highly impressed with the way his leading striker has come back in pre-season.
He has given a strong warning to League Two defenders, suggesting that Cook is in the best shape he has ever been.
Cook scored the opening goal in Tuesday’s friendly against Sunderland with a powerful finish, controlling the ball on his chest at the edge of the box and smashing it in off the post
He nearly added a remarkable second goal, attempting to beat keeper Simon Moore with a 40-yard half-volley.
Cook left the field midway through the second half to a standing ovation from the Valley Parade crowd, a recognition that Alexander felt was well-earned.
“He’s a Geordie, so he clearly enjoyed scoring against Sunderland!”
