Yes, I'd like to see videos dispalyed.
Seoane appeared pleased with training over the past week. He said the team had worked with great concentration and focus over the past few days. “We’ve tried to tackle the negative situation together. You can only reproduce a Bundesliga matchday in small sequences in training, but I felt lots of motivation and energy to work on the game plan together after the disappointment.”
In terms of the on-field aspects, the areas of challenges, communication and mentality were tackled: “It needs a hint more from everyone in the current situation in terms of these points,” the Swiss coach added. “We have to show willingness, above all in challenges, accepting the rigorousness and supporting each other.”
They want to remain loyal to their attacking play, but the current focus has clearly been on defending. “Obviously we want to excite the spectators, score lots of goals and have greater vigour in attack, but we can only do that when we work in a compact, determined and aggressive way against the ball beforehand,” continued Seoane, who also says that these include shoring up against the counter, an organised covering defence and clearer positioning after turnovers.
The 43-year-old has a clear goal for tomorrow’s game against Mainz: “We have to turn our words into actions and implement the things we’ve planned and trained.” Seoane believes the opposition is assured and determined: “Mainz play with confidence, especially at home, and play with a healthy dose of rigorousness and force. We want to stand up against that and play out our own situations well.”
Seoane expects to be able to draw upon the same squad as last weekend’s loss to Hoffenheim. Charles Aranguiz has trained individually due to muscular complaints but was again able to work with the team yesterday. If the Chilean midfielder has no problems in Friday’s final session, he’ll be available on Saturday.
The Werkself have sold 1,614 tickets for the game at the MEWA Arena and are looking forward to great support in Mainz.
