Arsenal sporting director Edu has admitted plans are already being put in place for this summer's transfer window.
The Gunners hold a five-point lead at the top of the Premier League table after last weekend's 3-0 win at Fulham.
January recruit Leonardo Trossard, who signed after Chelsea pipped Arsenal to the transfer of Ukraine winger Mykhailo Mudryk, set up all three goals at Craven Cottage to continue his fine start under Mikel Arteta.
Arsenal's swift move to bring in Trossard was widely praised and their sporting director insisted being 'well prepared' was key.
