FA Cup team news: Arsenal v Lincoln City
Arsenal will be without both Alex Iwobi and Danny Welbeck for Saturday's FA Cup sixth-round clash with Lincoln.
The pair have been struck down with illness while manager Arsene Wenger is sweating over Mesut Ozil, who is also sick.
Santi Cazorla (Achilles) and Mohamed Elneny (ankle) also miss out, with Wenger likely to make a number of changes for the visit of the Vanarama National League leaders.
Lincoln have been given permission to include Aston Villa left-back Riccardo Calder and Doncaster goalkeeper Ross Etheridge in their FA Cup quarter-final squad at Arsenal after signing the duo on loan.
Forward Lee Angol marked his Imps debut with a hat-trick for the National League leaders against Braintree on Tuesday night, but is cup-tied having played against Chelsea for parent club Peterborough in the third round.
Midfielder Josh Ginnelly, on loan from Burnley, is also ineligible after he made an appearance in the FA Cup during a spell with Walsall, while defender Lee Beevers has been out since the end of October with a knee problem.

Arsenal: Cech, Ospina, Martinez, Bellerin, Holding, Gabriel, Mertesacker, Koscielny, Mustafi, Monreal, Gibbs, Maitland-Niles, Coquelin, Xhaka, Ramsey, Oxlade-Chamberlain, Walcott, Reine-Adelaide, Perez, Sanchez, Giroud.
