Clarke, who watched as summer signing Jack Kiersey slotted home thirty-two minutes into the first half to secure a win for his travelling side, was pleased with the workout as the Saddlers enjoyed day two of their Polish pre-season Training Camp.
The Saddlers, who will face Notts County in their fifth pre-season outing of the summer next weekend, enjoyed plenty of possession against Odra Opole as they built upon Saturday's victory over Nuneaton Borough and added more much-needed match minutes whilst.
Clarke, who has overseen a complete squad overhaul since replacing Dean Keates earlier this year, praised his squad for being able to adapt as they faced previously unknown opposition just a couple of days after their most recent outing.
Speaking via the Express & Star's Walsall correspondent Joseph Masi, Darrell said; "It was another good work out for the boys. It’s been an intense couple of days.
"It was a different type of opposition but it was a good game and I felt we deserved to win it. The shape looked good at times and we got a great goal from Jack Kiersey which was pleasing.
"We didn’t know too much about them. We knew they were a full-time team in the Polish second division so it was always going to be a difficult challenge, they were quite a physical team as well.
"They moved the ball quite well. But I was pleased with our discipline and shape. It’s nice to have a game over here and win. They moved the ball well.
"It tends to be that way with foreign teams, they try and move the ball out from the back - pretty similar to our Premier League and Championship. But we shaped up really well without the ball and counter-attacked when we needed to."
