Arsenal are considering a transfer bid for Grenada left-back Guilherme Siqueira after he impressed scouts whilst on loan with Benfica, reports the Daily Mirror.
Although Arsene Wenger currently has both Nacho Monreal and Kieran Gibbs at his disposal, the Spanish international Monreal has been far from convincing since joining in January last year.
Meanwhile Siqueira has come of age whilst on loan in the Portuguese league and has attracted the attention of the Arsenal scouts as well as La Liga giants Real Madrid.
Los Blancos are scouring Europe for a new left-back as they plan to sell long-term Manchester United target Fabio Coentrao in the summer.
Marca reported on Saturday morning that Siqueira had been highlighted as the perfect back-up to Marcelo, who is set to be the first choice for the left-back berth for the foreseeable future.
A fee of €7m was agreed between Granada and Benfica, giving the Portuguese club the chance to make the move permanent, and would likely be available to any club for the same fee. That means the 27-year-old would represent excellent value as a back-up left-back.
For Arsenal that would most probably mean Monreal leaving the Emirates and could also play havoc with Manchester United's transfer plans this summer.
If Arsenal beat Real Madrid to their replacement left-back, Carlo Ancelotti may opt to keep Coentrao at the Bernabeu for another season.
David Moyes is in dire need of a new left-back at Old Trafford as Patrice Evra is expected to leave when his contract expires in June.
Wenger moving for Siqueira means Real Madrid will have to look at other targets and puts to possibility of Coentrao staying back on the table.
