Arsenal are close to finalising a deal with Sporting to sign Sweden forward Viktor Gyokeres.
The two clubs have been negotiating for more than a week with discussions now at an advanced stage and an agreement close.
Arsenal's most recent proposal for the 27-year-old totals about 70m euros (£60m) including add-ons.
Gyokeres has already agreed terms on a five-year deal with the Gunners, so once the finer details of the club-to-club agreement are agreed, the formalities of the move will be swiftly concluded.
BBC Sport revealed at the start of the month how Arsenal had turned their attentions to Gyokeres after hitting an impasse in their bid to sign Benjamin Sesko from RB Leipzig.
