马蒂厄·弗拉米尼(大腿伤)、塞斯克·法布雷加斯和赫莱布(都是腿后肌伤)都已恢复训练，正力争能够出战这场争冠征途中的重要大战。

Mathieu Flamini (thigh), Cesc Fabregas and Alex Hleb (both hamstring) are all back in training and fighting to be fit for what could be a pivotal game in the title race.

举个例子，为了伸拉你的股四头肌，先向右侧卧，然后用你的左手抓住你的左脚踝，将你的脚踝向你的腿后侧提拉。

For example, to stretch your quadriceps, lie on your right side and grasp your left ankle with your left hand, pulling your ankle toward the back of your leg.
