Laurent Koscielny was taken off during Arsenal's 3-0 win over BATE Borisov on ThursdayArsenal head coach Unai Emery says Laurent Koscielny was substituted during the Europa League win over BATE Borisov as a precaution. Koscielny, who missed the first four months of the season with an Achilles injury, received treatment on his left leg after being substituted. However, Emery has played down the severity of the injury and insists the France international was withdrawn as a precaution ahead of Sunday's home game against Southampton. Sokratis Papastathopoulos replaced Koscielny midway through the second half at the Emirates"It's a precaution. We'll know more tomorrow, but I hope he can be OK on Sunday or next week," said Emery.
