Per Mertesacker says Arsenal must be more decisive in front of goal when they face Barcelona on Tuesday night.
The Gunners were held to a 0-0 draw by Hull City in their FA Cup fifth-round tie at Emirates Stadium on Saturday.
Mertesacker was frustrated with the result, and accepts that the team will need to step up their performance levels against the European champions.
“We had a couple of good chances and we couldn’t keep the pressure as high as we wanted, especially in the second half,” he told Arsenal Player.
“We had enough chances to win, but we were unlucky at times. Overall it was disappointing, especially our finishing.
“We allowed [Hull goalkeeper Eldin Jakupovic] to make some decent saves because we were not that decisive.
“It is down to us, we produced a good defensive performance but overall in the final third, that little final pass at the end, we always rushed ourselves at times to finish so we need to learn from that.
“Overall, we missed a bit of something today and we have to come back quickly in three days time. We have a very important game, the first leg against Barcelona, and we will see the fans again, it will be another buzzing night but it is up to us how we perform.”Copyright 2016 The Arsenal Football Club plc.
