Hector Bellerin is a doubt for Saturday.

The young right back who is having something of a breakthrough season wasn’t in the squad for last week’s FA Cup tie against Middlesbrough, and could potentially be missing again this weekend.

On that occasion Calum Chambers replaced him, and with Mathieu Debuchy still on the long term casualty list, it looks as though Calum may be called upon again to play at full back against the in form Yannick Bolasie.

Speaking to Arsenal.com, Arsene Wenger confirmed that the young Spaniard is a doubt.

He said:

“We have some uncertainties about Flamini and Bellerin – they are doubtful for Saturday. Bellerin is his ankle and Flamini has a tight hamstring. We’ll see. We’ll have tests tomorrow [Friday].”

Hector’s last game was the home fixture against Leicester when he played the full 90 minutes, so it seems this niggle he has picked up must have been sustained in training.

The surprise package in defence this season, Bellerin has so far made 15 appearances in all competitions and scoring his first goal in the 5-0 walloping of Aston Villa. He has coped admirably with experienced opposition and it will be a blow if he is unable to shake off this injury.

Chambers is a capable deputy, but with only one league game under his belt since the turn of the year he may be a little rusty. Bolasie has shown himself to be a dangerous opponent this season and the young Englishman will need to be at the top of his game if he is to tame the Palace winger. Hopefully his winter breather has helped and he can get back to his early season form.
