Carabao Cup : Arsenal 5 Nottingham Forest 0 | Shkodran Mustafi sarcastically hits back at fan

'Sorry for keeping two clean sheets': Shkodran Mustafi sarcastically hits back at fan who begrudgingly points out Arsenal haven't conceded when he's been on the pitch this season

• A fan has begrudgingly pointed out Shkodran Mustafi's success this season 
• The German has made two starts in cup competitions and kept two clean sheets 
• Arsenal were keen to sell Mustafi this summer, but were unable to find a buyer

Shkodran Mustafi has sent a sarcastic apology to a fan on Twitter after his performances in defence for Arsenal so far this season.

The defender hasn't played in the Premier League yet, but has started in both the Europa League and the League Cup.

Arsenal didn't concede a goal in either game against Eintracht Frankfurt and Nottingham Forest, and one fan saw fit to point it out on Twitter.

Mustafi has started in the League Cup and Europa League, and kept a clean sheet in both

'I hate to say this but @MustafiOfficial has played two games and kept two clean sheet,' said the Twitter user, adding a 'thinking' emoji.

To white Mustafi replied: 'Sorry for keeping the two clean sheets,' adding a less than amused emoji of his own.

Mustafi was deemed surplus to requirements at Arsenal this summer, but the club were unable to find a buyer.

There was interest from Juventus on the final day, however the transfer window slammed shut before a deal was done. 

Mustafi joined Arsenal from Valencia for £35million in August 2016, but has fallen down the pecking order in recent times.

However, the German was given a start in the Gunners' 3-0 away win at Frankfurt, and then was in the line-up again for their 5-0 win against Forest in the League Cup.

After the Frankfurt game, Mustafi refused to rule out a potential transfer in the future, saying: 'My dad talked to the club. I am a player of Arsenal and have another two years of contract.

'I was never the one who starts a war when something does not work out.

'If something turns out, I'm open to taking the next step. If not, then I will continue my football.'
