Everton have completed the signing of the striker Lacina Traoré from Monaco despite concerns the deal would be scuppered by Radamel Falcao's cruciate injury.

The 6ft 8in Ivory Coast international underwent a medical on Merseyside on Sunday and was granted a work permit on Tuesday only for a serious injury to Falcao to put the transfer in doubt. Monaco were still prepared to let the 23-year-old leave and he has joined Roberto Martínez's team on loan until the end of the season.

Traoré is Everton's fourth loan signing of the campaign, the maximum allowed, under Premier League rules, and is expected to be their last acquisition of the January window. Martínez, who has already signed Aiden McGeady from Spartak Moscow, needed a forward having sold Nikica Jelavic to Hull City but a hamstring strain means the former Anzhi Makhachkala player is unlikely to be available for next Tuesday's derby at Liverpool.
