Fulham frontman Aleksandar Mitrovic was lucky to stay on the pitch after he saw red in a pre-season friendly bust-up.The Cottagers were facing Portuguese top flight side Estoril, when Harry Wilson was on the end of a late challenge. The big Serb didn't take too kindly to the challenge, and he squared up to Estoril midfielder Francisco Geraldes, grabbing the 27-year-old's shirt as he fumed at him.Mitrovic was quick to stand up for his team-mate as he continually shoved the Portuguese man backwards.
