Ronald Koeman believes his Southampton players understand the club’s decision to sell its top talents and has vowed to bring in replacements who are of equal quality or better than those who have left. “They know that’s the story in football, players come and go,” Koeman said. “The most important message I gave them was that we have to keep the philosophy and the ambition of the club. “If we lose some players we will bring in players of the same quality or even better quality if that is possible. “There is money to spend and to continue the quality and bring new players in.” Koeman carries great pedigree as a player having played for Holland and Barcelona, for whom he scored the winning goal in the 1992 European Cup final. The Dutchman’s arrival on the south coast has been overshadowed, however, by constant transfer speculation. The former Feyenoord boss admits it is important to convince the remaining players that Southampton is a club still moving forward. “We did that from the first day we came into the dressing room,” Koeman said. The Saints have already let striker Rickie Lambert and captain Adam Lallana join Liverpool while England left-back Luke Shaw was allowed to leave for Manchester United. Deals for all three players had been agreed before Koeman took the job at St Mary’s but the Dutchman insists the departures will not affect the morale of his squad.
