Wednesday's 4-0 drubbing at Chelsea, which left Atletico with little chance of progressing to the knockout stages of the Champions League, was the last straw for the club board who sacked boss Abel Resino on Friday morning and placed assistant Santi Denia in charge for Saturday's game.The midweek defeat came on the back of a terrible start to the season which has seen the Rojiblancos claim just one win in 10 matches.Lopez has vowed he and his fellow players will do all they can to make amends.Lopez admitted the players must take their share of the blame for a poor start to the season.It will not be an easy assignment for Denia against a Mallorca side whose fine start to the season continued with an excellent 3-1 win at home to Getafe last weekend.The islanders are not usually renowned for their home form, but have won all four games at Son Moix so far this term.Away from home, Mallorca have been less impressive, though, with two defeats and a draw from three games.Midfielder Borja Valero is taking nothing for granted, despite Atletico's horror week.Coach Gregorio Manzano should have a full-strength squad available for Saturday's match.For Atletico, Mariano Pernia could return to action following a long spell on the sidelines after being involved in a car crash earlier this year.For me home win here.
