Arsenal manager Unai Emery has been blocked from recalling Reiss Nelson and Calum Chambers.

As injuries have begun to pile-up at the Emirates, Emery is desperate for reinforcements this month.

However, BBC claims Nelson and Chambers will not be recalled from their successful loan spells.

18-year-old Nelson has excelled for Hoffenheim this season, while Chambers has also impressed with Arsenal's Premier League rivals, Fulham.

Emery has seen defenders Hector Bellerin, Rob Holding, Shkodran Mustafi, Nacho Monreal, Saed Kolasinac and Laurent Koscielny all to succumb to injuries in recent weeks.
