I think the forecast for the match between Proton Saratov (W) and Tula's Tula (W) will be a victory for the home team. Despite a series of 4 losses, Proton is always higher in the standings, while Tula shows good results only away, where they have 4 wins, although not against the strongest opponents. Therefore, I lean towards the conclusion that Proton will be able to overcome their previous failures and secure a victory on their home ground.
