Petr Cech is set to miss four weeks with a calf injury suffered against West Brom on Saturday.

The goalkeeper underwent a scan on Tuesday and the Gunners expect him to be out for around a month.

The injury means Cech will miss several crucial games for Arsenal, including next weekend’s clash against Manchester City.

He is also facing a race against time to be fit for the FA Cup semi final against Pep Guardiola’s side on April 23, though David Ospina is recognised as the club’s cup goalkeeper.

Ospina will deputise in Cech’s absence, but the Colombian international remains keen on leaving the Emirates this summer in a bid to play more regular football.

Meanwhile, Arsenal defender Hector Bellerin has emphasised his loyalty to Arsene Wenger amid ‘flattering’ transfer links to Barcelona and Manchester City.

There has been speculation of a possible swoop by Barcelona for Bellerin, and while the 22-year-old admits he finds it ‘special’ to be on Barca’s radar, he outlined his commitment to Arsenal by saying: ‘The loyalty to this person (Wenger) is worth more than money, it’s something very important to me, that he’s there carries a lot of weight for me.'
