Freddie Ljungberg says Arsenal will assess injuries to Kieran Tierney and Hector Bellerin after Monday's win over West Ham United.

Bellerin was named in the starting line-up but suffered a knock in the warm-up, while Tierney was taken off in the second-half with apparent shoulder injury.

"Tierney, I think it's something with his shoulder but I don't know exactly what it is," said Ljungberg after the 3-1 win. "But obviously we had to take him off so I think he's going to maybe go to hospital and check what it is.

"Hector had a bit of feeling, I think, in his hamstring in the warm up. Then we took the decision. I said I'm not going to force anyone to play if you don't feel 100 per cent.

"So we took him off and had a straight swap on that with Ainsley, and Ainsley had been out in the cold for a little bit and comes on and does really well, so I'm really proud of him and happy for him."
