Gabriel Jesus is expected to travel to Portugal with the Arsenal squad for their Europa League clash with Sporting CP.
However, it is very unlikely the Brazilian striker will be involved as he continues his recovery with his comeback set for after the international break, says The Sun.
Jesus, 25, has not featured for the Gunners since November 12 after suffering a knee injury at the Qatar World Cup that required surgery.
Arsenal have relied heavily on Eddie Nketiah in his absence, but boss Mikel Arteta could soon have his full-strength attacking line-up ready for the title run-in.
Jesus celebrated the north London club's dramatic 3-2 win over Bournemouth on the sidelines at the Emirates last weekend before taking part in a warm-down session on the pitch.
Jesus' progress means he is likely to fly out to Lisbon on Wednesday to take the next step in his rehabilitation.
