Hi Mr Dass,
Please pass this message to the students.
When doing entry pass, make sure your leg doesn't cross the line.
When there is a foul, quickly tap the ball and start. Don't waste time waiting or deciding who to tap.
Make use of 3 steps/side shooting. It will increase chances of scoring. If they are too close to the forbidden zone, do 1 or 2 step shooting.
Finally, do not argue among yourselves. Always stay focussed until the match is over. All the best to you and see you tomorrow.
