Koeman makes Lambert replacement Southampton priority
Lambert was sold to Liverpool before Koeman's appointment yesterday.
The Daily Mail says Koeman knows he will have limited funds to spend on strengthening his side this summer, but is understood to be interested in bringing 6ft 4ins striker Graziano Pelle with him from Feyenoord, while Heerenveen forward Alfred Finnbogason is also on his radar.
Money raised from player sales will be made available to Koeman in the summer transfer market.
