Baggies boss is confident side will improve...
A Didier Drogba hat-trick, Florent Malouda brace and a solitary strike from Frank Lampard did the damage against the Baggies and boss Di Matteo believes conceding a second goal just before half-time made things tough for his side.
He told ESPN: "The second goal was at a bad time, if we can go in at 1-0 there is still a chance for us, so we have to learn quickly."
The Baggies next face Sunderland at the Hawthorns in the Premier League, but Di Matteo is confident his side will improve after the 6-0 drubbing.
"We know there is quality, so we will keep working on it and we will improve. We will pick the players up, this is a tough place to come." he concluded.
