Roberto Martinez was impressed by the way Belgium rallied to secure a 1-1 World Cup qualifying draw with a "very good" Czech Republic side.

Lukas Provod put Czech Republic in front five minutes into the second half via a rasping drive from 20 yards out at Sinobo Stadium on Saturday.

Belgium hit back to salvage a point in Prague courtesy of Romelu Lukaku's seventh goal in his last six games for his country.

Czech Republic struck the woodwork twice and Kevin De Bruyne hit the post before Tomas Soucek's last-gasp header was cleared off the line by Belgium defender Toby Alderweireld.

The two nations have four points apiece after two Group E matches early in the battle to qualify for next year's tournament in Qatar, with Czech Republic top on goal difference.

Belgium manager Martinez was pleased with the way his team responded to falling behind, having also fought back to beat Wales 3-1 on Wednesday.

"We were put in difficulty by a very good Czech team and we had to adapt, to change our way of playing and responding," Martinez said.

"We were able to react and that's what I will remember from this match. We did not accept the situation after conceding the goal. We have to do better, of course, but I'm pretty happy with the team's reaction."

Martinez revealed Dries Mertens was withdrawn due to a shoulder injury, but was unsure over the extent of the damage.

The Spaniard refused to be drawn on whether in-form striker Lukaku and key midfielder De Bruyne will be rested when the top-ranked side in international football face Belarus on Tuesday.

"We will look at each case separately. We will first regenerate the bodies, because playing three matches in seven days is not easy." he said.
