Millwall gaffer Neil Harris wants his players to better control their fiery streaks and to brush up on defending free kicks.

He made his comments following the Lions’ 2-3 defeat to the hands of Portuguese side CD Tondela on Saturday, August 1.

Bold challenges and squabbles saw referee Lee Collins pull out a yellow card for John Marquis.

While Harris praised his side’s aggression, he said it needed to be channeled in the correct manner.

According to Newsatden he said: “There’s a difference between being a Millwall player and a Millwall team with aggression, passion and desire and being petulant and giving silly free-kicks away anywhere on the pitch.

“We want a flow to the game. We want the game to be fast and open, end to end, but if we’re giving cheap free-kicks away like we did (on Saturday) at times then the game’s not going to flow.”

The difference between the sides came in the form of Luis Tinoco’s in-swinger, which bypassed the Millwall back line to settle into the back of the net.
