Onana was hit with a 12-month suspension in February by UEFA after he failed a doping test last October.
The 25-year-old, backed by his club Ajax, have appealed against the ruling to the court of arbitration for sport, with the case due on Wednesday.
Despite the custodian being forced off to the sidelines, his stock has remained high across Europe with the likes of Manchester United, Paris Saint-Germain and Arsenal all expressing interest in him.
And according to Dutch broadcaster NOS, the Gunners are the favourites to land Onana’s signature this summer.
Arsenal are looking for an alternative for club number 1 Bert Leno between the sticks and have identified Onana as the ideal candidate.
It is claimed that the north London outfit will look to push for a move as soon as the verdict on Onana’s appeal is known, and will sort out the deal irrespective of whether the suspension remains.
If Onana’s punishment is shortened, Ajax will look for a fee in the €6m to €9m range while if the sentence stands, they will have to settle for €2m.
Either way, the Dutch giants will make a profit on the €150,000 they paid Barcelona for Onana’s signature in 2015, provided they reach an agreement with Arsenal.
