Arsenal manager Mikel Arteta has urged his side to stop giving away so many sloppy goals following Thursday's 2-2 draw against Sporting CP.
The north London outfit travelled to Lisbon for he first leg of their Europa League round of 16 clash and they took the lead in the 22nd minute through defender William Saliba. The French international headed home a perfectly-weighted Fabio Vieira corner before the Portuguese side struck level shortly after following a corner of their own.
Paulinho gave Sporting the lead shortly after half-time but the Gunners quickly struck back thanks to a freak own goal from Japanese international Hidemasa Morita. After the full-time whistle, Arteta voiced his frustrations at his defenders, urging his team to improve their defensive organisation.
