The situation looked good following the Muur, with Moscon and Rowe ensconced in a strong group, with a number of big names having missed the move. The gap spun out to one minute, but the peloton eventually got organised and hauled it back - but not before Rowe had gone down and Gilbert had escaped to victory.
Back at the team bus Sport Director Servais Knaven added: "I think tactically it worked out well. The plan was to hit the Muur hard and we had a feeling Quick-Step would do the same. After that we had Luke and Gianni up there with three Quick-Step guys - 14 riders in total. That was a perfect situation. They took more than a minute but the gap began to come down before the second climb of the Kwaremont.
"Then Gilbert went and we were still in a good position with two guys behind him. Then Luke crashed with Vanmarcke and we lost him there. Gianni was on his own and he did a really good ride. He's still young and it's hard on your own. But I'm proud of him and he can be proud of himself.
"As a team the guys were really good and strong riding together. They made sure everyone was in a good position on the Muur which was impressive."
