Schalke have taken aim at Queens Park Rangers via a strongly-worded statement after transfer talks between the clubs went south.The German side revealed that QPR had already agreed terms to sign striker Pape Meissa Ba twice this summer.QPR have come close to signing Schalke striker Ba twice this summerGettyHowever, a deal has not been completed, and they are putting the blame on the Championship outfit.In a statement on Schalke’s website, they wrote: “Despite FC Schalke 04 and Queens Park Rangers having twice reached an agreement over the transfer of Pape Meïssa Ba, the move will now not go ahead. “The English Championship side informed the Royal Blues of their decision in the early hours of Wednesday.”Schalke’s board member for sport, Frank Baumann, then slammed QPR for their approach to trying to sign Ba.“We are very frustrated with QPR’s conduct over the past two weeks,” Baumann said in a strongly worded statement.“This period has been marked by delays without any substantive explanation, as well as days without any response to calls or official messages. “For us, a transfer – especially after two agreements between the clubs – should be handled in a more cooperative manner.” Baumann also stated that the club had purposely stopped themselves from commenting publicly to maintain respect for the player and the situation.It appears that QPR pulled out of a deal to sign the Schalke striker due to concerns over his fitness.He continued: “Pape has made over 30 competitive appearances in each of the past four years, and was in good physical condition during our pre-season preparations.QPR have been massively criticised for their actions in talks with SchalkeGETTY“The concerns raised by Queens Park Rangers are not new – they have already been taken into account in four previous transfers. “They clearly do not prevent him from carrying out his duties as a professional footballer, as his average of more than 30 matches per season demonstrates. “Our priority now is to get Pape back into training as quickly as possible.”Ba is a 28-year-old striker who only signed for Schalke in January from French side Grenoble.He netted two goals in 13 appearances in the 2. Bundesliga, following his tally of over 50 goals in Ligue 2 and below in France.It seems QPR were very interested in bringing him to England, but they’ve now opted not to go ahead with the move.Ba now looks to be staying at Schalke as QPR has fitness concernsGettyMore Schalke dramaStrangely, this is the first time this year that Schalke has been involved in a spat with an EFL club.In May, their move for Miron Muslic led to Plymouth Argyle taking aim at the manager as he left for Germany.Muslic was appointed Schalke boss three months ago after he quit Plymouth following their relegation to League One. The departure came after Argyle released a statement to admit they had ‘reluctantly allowed’ talks to begin.It read: “Despite regular communication since the end of the season, and no mention of any issues, Miron has now made it clear that, after extended periods away from his family, this opportunity provides him the chance to be closer to them after four years on the road.“We are frustrated by this decision, having implemented clear structures, processes and personnel to aid Miron and his coaching staff as we look to return to the Sky Bet Championship at the earliest opportunity.Muslic left Plymouth for Schalke in controversial circumstancesAFP“Not only that, the club have also moved quickly to bring in new signings and received repeated verbal promises from Miron that he was committed to Argyle and would do everything to help the club bounce back to the second tier.”Plymouth owner Simon Hallett was then left raging after Muslic officially joined Schalke, writing an open letter to fans.Hallett claimed Muslic could never return to the club and criticised him for his approach to leaving his role. The manager is now back involved in drama with a team in the EFL, a few months after leaving for Germany. QPR are going to have to move on to other targets, while Muslic appears to be keeping Ba in his set-up. In their opening two games of the 2. Bundesliga, Schalke has won one and lost one, with VFL Bochum their next opponents.
